103-688: Besides shipbuilding, Deutsche Werke also produced firearms . Especially well-known are the so-called Ortgies pistols , which were particularly popular in the United States . The pistols were developed by Heinrich Ortgies . Deutsche Werke started building merchant ships , but when the Nazi Party gained power in 1933 the production was changed to naval ships . During World War II the company expanded to Gdynia , establishing Deutsche Werke Gotenhafen . Deutsche Werke facilities and infrastructure were destroyed during World War II by bombing raids . Parts of

206-454: A Precision Sniper Rifle (PSR) called for 1 MOA (0.3 mrad) extreme vertical spread for all shots in a 5-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters. In 2009, a United States Special Operations Command market survey called for a 1 MOA (0.28 mrad) extreme vertical spread for all shots in a 10-round group fired at targets at 300, 600, 900, 1,200, and 1,500 meters. The 2009 Precision Sniper Rifle requirements state that

309-404: A bolt action or semi-automatic action , fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge . The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed in 1854 by Sir Joseph Whitworth , a prominent British engineer, it used barrels with hexagonal polygonal rifling , which meant that

412-553: A retronym to differentiate older full-powered rifles of these configurations like the M1 Garand , from newer assault rifles using intermediate cartridges like the Heckler & Koch HK33 , but it is sometimes used to describe similar modern rifles such as the FN SCAR . Battle rifles serve similar purposes as assault rifles, as they both are usually employed by ground infantry for essentially

515-445: A riot gun or breaching rounds to function as a door breaching shotgun. Shotgun munitions, regardless of type, are packed into shotgun shells (cartridges designed specifically for shotguns) that are loaded into the shotgun for use; these shells are commonly loose and manually loaded one-by-one, though some shotguns accept magazines. Shotguns share many qualities with rifles, such as both being descendants of early long guns such as

618-453: A 2-inch shot group at 200 yards) before being released for fielding. Although accuracy standards for police rifles do not widely exist, rifles are frequently seen with accuracy levels from 0.5 to 1.5 MOA (0.2–0.5 mrad). For typical policing situations, an extreme spread accuracy level no better than 1 MOA (0.3 mrad) is usually all that is required, as police typically employ their rifles at shorter ranges. At 100 m (109 yd) or less,

721-465: A 5-shot group at 1,500 meters when fired from a supported, non-benchrest position". The M24 Sniper Weapon System adopted in 1988 has a stated maximum effective range of 800 meters and a maximum allowed average mean radius (AMR) of 1.9 inches at 300 yards from a machine rest, which corresponds to a 0.6 MOA (0.17 mrad) extreme spread for a 5-shot group when using 7.62×51mm M118 Special Ball cartridges. A 2008 United States military market survey for

824-476: A 69% probability that the bullet's point of impact will be in a target circle with a diameter of 23.3 cm (9.2 in) at 800 m (875 yd). This average extreme spread for a 5-shot group and the accompanying hit probability are considered sufficient for effectively hitting a human at an 800-meter distance. In 1982, a U.S. Army draft requirement for a Sniper Weapon System was: "The System will: (6) Have an accuracy of no more than 0.75 MOA (0.2 mrad) for

927-663: A broad class of rifles generally summed up as short, lightweight, portable sniper rifles; and designated marksman rifles , semi-automatic high-precision rifles, usually chambered in intermediate or full-power cartridges, that fill the range gap between sniper rifles and regular rifles and are designed for designated marksmen in squads. Examples of sniper and scout rifles include the M40 rifle , Heckler & Koch PSG1 , Walther WA 2000 , Accuracy International AWM , M24 Sniper Weapon System , Steyr Scout , Sako TRG , and CheyTac Intervention . Examples of anti-materiel and anti-tank rifles include

1030-423: A full-power caliber and a certain weight that can be operated by an individual but tend to work best with a crew; and heavy machine guns , machine guns that are too large and heavy to be carried and are thus mounted to something (like a tripod or military vehicle ), and require a crew to operate. A general-purpose machine gun combines these categories under a single flexible machine gun platform, often one that

1133-625: A full-size rifle with a shortened carbine-style barrel for close-quarters use. The small size of a carbine provides lighter weight and better maneuverability, making them ideal for close-quarters combat and storage in compact areas. This makes them popular firearms among special forces and police tactical units alongside submachine guns , considerably so since the late 1990s due to the familiarity and better stopping power of carbines compared to submachine guns. They are also popular with (and were originally mostly intended for) military personnel in roles that are expected to engage in combat, but where

1236-452: A full-size rifle would be an impediment to the primary duties of that soldier ( logistical personnel, airborne forces , military engineers , officers , etc.), though since the turn of the millennium these have been superseded to a degree in some roles by personal defense weapons . Carbines are also common among civilian firearm owners who have size, space, and power concerns similar to military and police users. Examples of carbines include

1339-793: A method of effective self-defense against skirmishers and infiltrators who cannot effectively be defeated by low-powered submachine guns and handguns, often the only firearms suitable for those personnel (while they could be issued rifles or carbines, those would become unnecessary burdens in their normal duties, during which the likelihood of hostility is fairly rare regardless, making their issuance questionable). Thus, per their name, personal defense weapons allow these personnel to effectively defend themselves from enemies and repel attacks themselves or at least until support can arrive. They are not intended for civilian self-defense due to their nature as automatic firearms (which are usually prohibited from civilian purchase), though some semi-automatic PDWs exist for

1442-403: A much larger objective lens (40 to 50 mm in diameter) for a brighter image. Most telescopic lenses employed in military or police roles also have special reticles to aid with judgment of distance, which is an important factor in accurate shot placement due to the bullet's trajectory. The choice between bolt-action and semi-automatic , usually recoil operation or gas operation for

1545-575: A range of 2,000 yards (around 1,830 meters), whereas the Enfield could only manage it at a distance of 1,400 yards (around 1,280 meters). During the American Civil War , Confederate sharpshooters equipped with Whitworth rifles were tasked to kill Union field artillery crews, and were responsible for killing Major General John Sedgwick —one of the highest-ranking officers killed during the Civil War—at

1648-445: A rifle with a relatively low accuracy of only 1 MOA (0.3 mrad) should be able to repeatedly hit a 3 cm (1.2 inch) target. A 3 cm diameter target is smaller than the brain stem , which is targeted by police snipers for its quick killing effect. Unlike police sniper rifles, military sniper rifles tend to be employed at the greatest possible distances, so that range advantages, like an increased difficulty to spot and engage

1751-430: A safe distance and penetrating reinforced structures that enemy combatants are using as cover. A designated marksman rifle (DMR) is less specialized than a typical military sniper rifle, often only intended to extend the range of a group of soldiers. Therefore, when a semi-automatic action is used, it is due to an overlap with the roles of standard-issue weapons. There may also be additional logistical advantages if

1854-469: A single soldier, though some are crew-served weapons that require a dedicated crew of soldiers to operate, usually between two and six soldiers depending on the machine gun's operation and the crew members' roles (ammunition bearers, spotters, etc.). Machine guns can be divided into three categories: light machine guns , individual-served machine guns of an intermediate cartridge that are usually magazine-fed; medium machine guns , belt-fed machine guns of

1957-467: A sniper rifle cartridge instead of trying to break new ground with less-perfected (but possibly better) ammunition. Before the introduction of the standard 7.62×51mm NATO (.308 Winchester) cartridge in the 1950s, standard military cartridges were the .30-06 Springfield (7.62×63mm) (United States), .303 British (7.7×56mmR) (United Kingdom), and 7.92×57 mm Mauser (Germany). The .30-06 Springfield continued in service with U.S. Marine Corps snipers during

2060-410: A time by the user, rather than automatically. Manual action firearms can be divided into two basic categories: single-shot firearms that can only be fired once per barrel before it must be reloaded or charged via an external mechanism or series of steps; and repeating firearms that can be fired multiple times per barrel, but can only be fired once with each subsequent pull of the trigger or ignite, and

2163-551: Is a long gun that has a predominantly smoothbore barrel—meaning it lacks rifling—designed to fire a number of shot pellets in each discharge. These shot pellet sizes commonly range between 2 mm #9 birdshot and 8.4 mm #00 (double-aught) buckshot, and produce a cluster of impact points with considerably less range and accuracy, since shot spreads during flight. Shotguns are also capable of firing single solid projectiles called slugs , or specialty (often " less lethal ") munitions such as bean bags or tear gas to function as

SECTION 20

2266-616: Is a magazine-fed carbine chambered in a small-caliber handgun cartridge (such as 9×19mm Parabellum , .45 ACP , .22 Long Rifle , and .40 S&W ). They cannot be considered machine guns due to their small-caliber, hence the prefix " sub- " to differentiate them from proper machine guns. Submachine guns are commonly associated with high rates of fire, automatic fire capabilities, and low recoil, though many submachine guns differentiate from this in various ways, such as having fairly low rates of fire or including burst and semi-automatic modes available through selective fire. Most submachine guns are

2369-417: Is any firearm with a notably long barrel, typically a length of 10 to 30 inches (250 to 760 mm) (there are restrictions on minimum barrel length in many jurisdictions; maximum barrel length is usually a matter of practicality). Unlike a handgun, long guns are designed to be held and fired with both hands, while braced against either the hip or the shoulder for better stability. The receiver and trigger group

2472-424: Is marketed to, law enforcement rather than military agencies. The features of a sniper rifle can vary widely depending on the specific tasks it is intended to perform. Features that may distinguish a sniper rifle from other weapons are the presence of a telescopic sight , unusually long overall length, a stock designed for firing from a prone position , and the presence of a bipod and other accessories. Perhaps

2575-540: Is most suitable as a light or medium machine gun but fares well as a heavy machine gun. A closely related concept is the squad automatic weapon , a portable light machine gun or even a modified rifle that is designed and fielded to provide a squad with rapid direct fire . Examples of machine guns include the Maxim gun , M2 Browning , Bren light machine gun , MG 42 , PK machine gun , FN MAG , M249 light machine gun , RPK , IWI Negev , and M134 Minigun . A submachine gun

2678-467: Is mounted into a stock made of wood, plastic, metal, or composite material, which has sections that form a foregrip, rear grip, and optionally (but typically) a shoulder mount called the butt . Early long arms, from the Renaissance up to the mid-19th century, were generally smoothbore firearms that fired one or more ball shot, called muskets or arquebuses depending on caliber and firing mechanism. Since

2781-404: Is that the bullet only interacts after a relatively long flight path with the target (which can also be a materiel target for a sniper bullet). This implies that variables such as the minimal required hit probability, local atmospheric conditions, properties and velocity of the employed bullet (parts), properties of the target, and the desired terminal effect are major relevant factors that determine

2884-592: Is towards larger calibers that offer relatively favorable hit probabilities at greater range with anti-personnel cartridges, such as .300 Winchester Magnum and .338 Lapua Magnum, and anti-materiel cartridges, such as 12.7×99mm , 12.7×108mm , and 14.5×114mm . This allows snipers to take fewer risks and spend less time finding concealment when facing enemies that are not equipped with similar weapons. Maximum range claims made by military organizations and materiel manufacturers regarding sniper weapon systems are not based on consistent or strictly scientific criteria. The problem

2987-408: Is typically capable of 1–3 MOA (0.3–0.9 mrad) accuracy, with a police sniper rifle capable of 0.25–1.5 MOA (0.1–0.4 mrad) accuracy. For comparison, a competition target or benchrest rifle may be capable of accuracy up to 0.15–0.3 MOA (0.04–0.09 mrad). A 1 MOA (0.28 mrad) average extreme spread (the center-to-center distance between the two most distant bullet holes) for a 5-shot group translates into

3090-428: Is unimportant at closer ranges; the impact velocity of the bullet is more than sufficient. The most common special feature of a sniper rifle stock is the adjustable cheek piece, where the shooter's cheek meets the rear of the stock. For most rifles equipped with a telescopic sight, this area is raised slightly because the telescope is positioned higher than iron sights , and can sometimes be adjusted up or down to suit

3193-488: Is usually crowned or machined to form a rebated area around the muzzle proper to avoid asymmetry or damage, and consequent inaccuracy. External longitudinal fluting that contributes to heat dissipation by increasing the surface area, while simultaneously decreasing the weight of the barrel, is sometimes used on sniper rifle barrels. Sniper-rifle barrels may also utilize a threaded muzzle or combination device ( muzzle brake or flash suppressor and attachment mount) to allow

3296-584: The 7mm Remington Magnum (7.2×64mm), .300 Winchester Magnum (7.62×67mm), and the .338 Lapua Magnum (8.6×70mm). These cartridges offer better ballistic performance and greater effective range than the 7.62×51mm. Though they are not as powerful as .50 caliber cartridges, rifles chambered for these cartridges are not as heavy as those chambered for .50 caliber ammunition, and are significantly more powerful than rifles chambered for 7.62×51mm. Snipers may also employ anti-materiel rifles in sniping roles against targets such as vehicles, equipment and structures, or for

3399-520: The AK-74 and AKS-74U . However, some carbines, such as the M1 carbine , are not a variant of any existing design and are their own firearm model. Carbines are regardless very similar to rifles and often have the same actions (single-shot, lever-action, bolt-action, semi-automatic, automatic, etc.). This similarity has given carbines the alternate name of short barreled rifle (SBR), though this more accurately describes

3502-525: The Battle of Spotsylvania Court House . During the Crimean War, the first optical sights were designed for fitting onto the rifles. Much of this pioneering work was the brainchild of a Colonel D. Davidson, using optical sights produced by Chance Brothers of Birmingham . This allowed a marksman to more accurately observe and target objects at a greater distance than ever before. The telescopic sight, or scope,

3605-587: The FG 42 , Gewehr 43 , FN FAL , Howa Type 64 , and Desert Tech MDR . A sniper rifle is, per widespread definition, a high-powered precision rifle, often bolt-action or semi-automatic, with an effective range farther than that of a standard rifle. Though any rifle in a sniper configuration (usually with a telescopic sight and bipod ) can be considered a sniper rifle, most sniper rifles are purpose-built for their applications, or are variants of existing rifles that have been modified to function as sniper rifles, such as

3708-589: The Glock , Browning Hi-Power , M1911 pistol , Makarov pistol , Walther PP , Luger pistol , Mauser C96 , and Beretta 92 . Examples of revolvers include the Colt Single Action Army , Smith & Wesson Model 10 , Colt Official Police , Colt Python , New Nambu M60 , and Mateba Autorevolver . Examples of derringers include the Remington Model 95 , FP-45 Liberator , and COP .357 Derringer . A long gun

3811-459: The Karabiner 98k and Mosin–Nagant Model 1891/30 sniper rifle , had a drastic and demoralizing effect on the battlefield. Soldiers would often remain hidden in foxholes or trenches so as not to expose themselves to the deadly accuracy of a sniper. Some soldiers even began to disregard orders from commanding officers to protect against potential harm, which thus broke down the chain of command on

3914-599: The Lee–Metford rifle, while the Boers had received the latest Mauser Model 1895 rifles from Germany. In the open terrain of South Africa , the marksman was a crucial component in battle. The Lovat Scouts was a British Army unit formed in 1899 that was renowned for the expert marksmanship and stalking skills of its personnel. The men wore ghillie suits for camouflage and were expertly skilled in observation. Hesketh Hesketh-Prichard said of them that "keener men never lived". After

4017-592: The M110 SASS , are used in similar "target-rich" environments. In a military setting, logistical concerns are the primary determinant of the cartridge used, so sniper rifles are usually limited to rifle cartridges commonly used by the military force employing the rifle and match grade ammunition. Since large national militaries generally change slowly, military rifle ammunition is frequently battle-tested and well-studied by ammunition and firearms experts. Consequently, police forces tend to follow military practices in choosing

4120-688: The M110 Semi-Automatic Sniper System , which has a maximum allowed extreme spread of 1.8 MOA (0.5 mrad) for a 5-shot group on 300 feet, using M118LR ammunition or equivalent. In 2010, the maximum bullet dispersion requirement for the M24 .300 Winchester Magnum corresponded to 1.4 MOA (0.39 mrad) extreme spread for 5 shot group on 100 meters. In 2011, the US military adapted the .300 Winchester Magnum M2010 Enhanced Sniper Rifle , which had to meet an accuracy requirement to fire ≤ 1 MOA/0.28 mrad (less than

4223-500: The M26 Modular Accessory Shotgun System . Shotguns are still popular with civilians for the suitability of their shot spread in hunting, clay pigeon shooting , and home defense. Double-barreled shotguns are break-action shotguns with two parallel barrels (horizontal side-by-side or vertical over-and-under), allowing two single shots that can be loaded and fired in quick succession. Examples of shotguns include

A personal defense weapon is, in simplest terms, a submachine gun that is designed to fire ammunition with ballistic performance that is similar to (but not actually a type of) rifle cartridges, often called "sub-intermediate" cartridges. In this way, it combines

4429-649: The Mauser Tankgewehr M1918 , Boys anti-tank rifle , PTRS-41 , Barrett M82 , Gepárd anti-materiel rifle , and McMillan TAC-50 . Examples of designated marksman rifles include the SVD , SR-25 , Dragunov SVU , Marine Scout Sniper Rifle , Mk 14 Enhanced Battle Rifle , and M110 Semi-Automatic Sniper System . An automatic rifle is a magazine-fed rifle that is capable of automatic fire. They include most assault rifles and battle rifles, but originated as their own category of rifles capable of automatic fire, as opposed to

4532-459: The Munich massacre at the 1972 Summer Olympics . Many police services and law enforcement organizations (such as the U.S. Secret Service ) now use rifles designed for law enforcement purposes. The Heckler & Koch PSG1 is one rifle specifically designed to meet these criteria and is often referred to as an ideal example of this type of sniper rifle. The FN Special Police Rifle was built for, and

4635-784: The National Firearms Act and Firearm Owners Protection Act define a "machine gun" in United States Code Title 26, Subtitle E, Chapter 53, Subchapter B, Part 1, § 5845 as "... any firearm which shoots ... automatically more than one shot, without manual reloading, by a single function of the trigger". "Machine gun" is therefore largely synonymous with "automatic weapon" in American civilian parlance, covering all automatic firearms. In most jurisdictions, automatic rifles, as well as automatic firearms in general, are prohibited from civilian purchase or are at least heavily restricted; in

4738-475: The Raufoss Mk 211 projectile. Due to the considerable size and weight of anti-materiel rifles, two- or three-man sniper teams become necessary. Barrels are normally of precise manufacture and of a heavier cross section than more traditional barrels, in order to reduce the change in impact points between a first shot from a cold barrel and a follow-up shot from a warm barrel. Unlike many battle and assault rifles,

4841-638: The Springfield Armory (United States), the Royal Small Arms Factory (United Kingdom), Mauser (Germany), Steyr-Daimler-Puch (Austria), and Rock Island Armory under Armscor (Philippines). As of 2018 the Small Arms Survey reported that there were over one billion firearms distributed globally, of which 857 million (about 85 percent) were in civilian hands. U.S. civilians alone account for 393 million (about 46 percent) of

4944-464: The StG 44 produced by Nazi Germany during World War II , assault rifles have since become extremely popular among militaries and other armed groups due to their universal versatility, and they have made up the vast majority of standard-issue military service rifles since the mid-20th century. Various configurations of assault rifle exist, such as the bullpup , in which the firing grip is located in front of

5047-539: The Type 97 sniper rifle , which was essentially a standard Type 38 rifle that was modified to be lighter and come with a telescopic sight. Related developments are anti-materiel rifles , large-caliber rifles designed to destroy enemy materiel such as vehicles, supplies, or hardware; anti-tank rifles , anti-materiel rifles that were designed specifically to combat early armoured fighting vehicles , but are now largely obsolete due to advances in vehicle armour ; scout rifles ,

5150-621: The Vietnam War in the 1970s, well after general adoption of the 7.62×51mm. At the present time, in both the Western world and within NATO , the 7.62×51mm is currently the primary cartridge of choice for military and police sniper rifles. Worldwide, the trend is similar. The preferred sniper cartridge in Russia is another .30 caliber military cartridge, the 7.62×54mmR , which has slightly superior performance to

5253-520: The Winchester Model 1892 , Rifle No. 5 Mk I , SKS , M1 carbine , Ruger Mini-14 , M4 carbine , and Kel-Tec SUB-2000 . An assault rifle is commonly defined as a selective-fire rifle chambered in an intermediate cartridge (such as 5.56×45mm NATO , 7.62×39mm , 5.45×39mm , and .300 AAC Blackout ) and fed with a detachable magazine . Assault rifles are also usually smaller than full-sized rifles such as battle rifles . Originating with

A carbine is a long gun, usually a rifle, that has had its barrel shortened from its original length or is of a certain size smaller than standard rifles, but is still large enough to be considered a long gun. How considerable

Examples of assault rifles include the Kalashnikov rifles of Soviet and Russian origin (such as the AK-47 , AKM , and AK-74 ), as well as the American M4 carbine and M16 rifle . A battle rifle is commonly defined as a semi-automatic or selective-fire rifle that is larger or longer than an assault rifle and is chambered in a "full-power" cartridge (e.g. 7.62×51mm NATO , 7.92×57mm Mauser , 7.62×54mmR ). The term originated as

Requirements include high accuracy, reliability, and mobility, concealment, and optics, for anti-personnel , anti-materiel and surveillance uses by military snipers . The modern sniper rifle is a portable shoulder-fired rifle with either

5665-865: The 19th and 20th centuries, various types of long guns have been created for different purposes. A rifle is a long gun that has riflings (spiral grooves) machined into the bore (inner) surface of its barrel, imparting a gyroscopically stabilizing spin to the bullets that it fires. A descendant of the musket, rifles produce a single point of impact with each firing with a long range and high accuracy. For this reason, as well as for their ubiquity, rifles are very popular among militaries as service rifles , police as accurate long-range alternatives to their traditional shotgun long guns, and civilians for hunting , shooting sports , and self-defense . Many types of rifles exist owing to their wide adoption and versatility, ranging from mere barrel length differences as in short-barreled rifles and carbines , to classifications per

5768-426: The 20th century, but have since been superseded in most combat roles by rifles, carbines, and personal defense weapons due to their low effective range and poor penetration against most body armor developed since the late 20th century. However, they remain popular among special forces and police for their effectiveness in close-quarters and low likelihood to overpenetrate targets. Examples of submachine guns include

5871-472: The 7.62×51mm, although the rimmed design limits reliability compared to the latter cartridge. This cartridge was introduced in 1891, and both Russian sniper rifles of the modern era, the Mosin–Nagant and the SVD , are chambered for it. Certain commercial cartridges designed with only performance in mind, without the logistical constraints of most armies, have also gained popularity in the 1990s. These include

5974-565: The Boer War, the Scouts became the first official sniper unit in the British Army. It was not until World War I that sniper rifles began to be used more regularly in battle and certain soldiers given specialized training to use such a rifle. In Germany, these trained snipers were given rifles with telescopic sights, which illuminated at night in order to improve their accuracy. German gunsmiths fitted

6077-538: The DMR uses the same ammunition as the more common standard-issue weapons. These rifles enable a higher volume of fire, but sacrifice some long-range accuracy. They are frequently built from existing selective fire battle rifles or assault rifles, often simply by adding a telescopic sight and adjustable stock. A police semi-automatic sniper rifle may be used in situations that require a single sniper to engage multiple targets in quick succession; military semi-automatics, such as

6180-468: The PSR, when fired without a suppressor, shall provide a confidence factor of 80% that the weapon and ammunition combination is capable of holding 1 MOA (0.28 mrad) extreme vertical spread, calculated from 150 ten-round groups that were fired unsuppressed. No individual group was to exceed 1.5 MOA (0.42 mrad) extreme vertical spread. All accuracy was taken at the 1,500 meter point. In 2008, the US military adopted

6386-426: The battlefield. The sniper rifle soon acquired the reputation of being one of the most effective and ruthless weapons of war. Though sniper rifles had proved to be extremely effective in combat, there was still a great reluctance in many militaries to adopt a trained sniper regiment . To effectively use a sniper rifle, a soldier had to go through particularly rigorous training, and most trainees did not make it past

6489-839: The bolt-action and semi-automatic rifles commonly issued to infantry at the time of their invention. They usually have smaller magazine capacities than machine guns ; the French Chauchat had a 20-round box magazine, while the Hotchkiss Mle 1914 machine gun , the French Army 's standard machine gun at the time, was fed by a 250-round ammunition belt . Though automatic rifles are sometimes considered to be their own category, they are also occasionally considered to be other types of firearms that postdated their invention, usually as light machine guns . Automatic rifles are sometimes confused with machine guns or vice versa, or are defined as such by law;

6592-408: The bores are usually not chromed to avoid inaccuracy due to an uneven treatment. When installed, barrels are often free-floating —installed so that the barrel contacts the rest of the rifle only at the receiver. A free-floating barrel avoids contact with the fore-end of the stock by the barrel itself, sling, bipod, or the sniper's hands that can interfere with barrel harmonics. The end of the barrel

Types aside, firearms are also categorized by their "action", which describes their loading, firing, and unloading cycle. Manual action or manual operation is essentially any type of firearm action that is loaded, and usually also fired, one cartridge at

Shooters aim firearms at their targets with hand-eye coordination , using either iron sights or optical sights . The accurate range of pistols generally does not exceed 100 metres (110 yd; 330 ft), while most rifles are accurate to 500 metres (550 yd; 1,600 ft) using iron sights, or to longer ranges whilst using optical sights. Purpose-built sniper rifles and anti-materiel rifles are accurate to ranges of more than 2,000 metres (2,200 yd). (Firearm rounds may be dangerous or lethal well beyond their accurate range;

6901-507: The difference is between a rifle and a carbine varies; for example, the standard Heckler & Koch G36 's barrel has a length of 480 mm (18.9 in), the G36K carbine variant's barrel is 318 mm (12.5 in), and the G36C compact variant's barrel is 228 mm (9.0 in). Some carbines are also redesigned compared to their rifle counterparts, such as the aforementioned G36/G36K and G36C, or

7004-462: The effective range of sniper rifles (c. 2001) exceeding 1,000 m (1,094 yd), making them one of the most accurate and efficient weapons in use. Modern sniper rifles can be divided into two basic classes: military and law enforcement. Sniper rifles manufactured for military service are often designed for very high durability, range, reliability, sturdiness, serviceability, and repairability under adverse environmental and combat conditions, at

7107-423: The firearm's action must be reloaded or charged via an internal mechanism between trigger pulls. Types of manual actions include lever action, bolt action, and pump action. Lever action is a repeating action that is operated by using a cocking handle (the "lever") located around the trigger guard area (often incorporating it) that is pulled down then back up to move the bolt via internal linkages and cock

7210-461: The first week. Sniper training was also so expensive to conduct that, even until as recently as 1970, the reasoning for having trained snipers as a part of an army was deemed questionable. In Britain, sniper rifles were not seen as being an integral part of an army until after the Germans boasted of their success with sniper teams during the early months of World War I. British army advisors supposed that

7313-456: The fitting of a suppressor . These suppressors often have a means of adjusting the point of impact while fitted. Military sniper rifles tend to have barrel lengths of 610 mm (24 in) or longer to allow the cartridge propellant to fully burn, reducing the amount of revealing muzzle flash and increasing muzzle velocity. Police sniper rifles may use shorter barrels to improve handling characteristics. The shorter barrels' muzzle velocity loss

7416-403: The global total of small arms. A handgun is, as defined generally and in many gun laws , a firearm that can be used with a single hand. They are the smallest of all firearms, and are common as sidearms , concealed carry weapons, or as backup weapons for self-defense . Handguns can be categorized into two broad types: pistols , which have a single fixed firing chamber machined into

7519-470: The greatest possible accuracy, but do not need to have as long a range. Law enforcement-specific rifles are usually used in non-combat (often urban) environments, so they do not have the requirement to be as hardy or portable as military versions; they may also be smaller due to the decrease in required range. Some of the first sniper rifles designed specifically to meet police and other law-enforcement requirements were developed for West German police after

7622-457: The high automatic rate of fire, reliable low recoil, and lightweight compact maneuverability of submachine guns with the versatility, penetration, and effective range of rifles, effectively making them an "in-between" of submachine guns and carbines. Personal defense weapons were developed to provide rear and "second-line" personnel not otherwise armed with high-caliber firearms (vehicle and weapon crews, engineers, logistical personnel, etc.) with

7725-400: The individual shooter. To further aid this individual fitting, the stock can sometimes also be adjusted for length, often by varying the number of inserts at the rear of the stock where it meets the shooter's shoulder. If the stock is manufactured from wood, environmental conditions or operational use may warp the wood , causing slight alignment or barrel harmonics changes over time and altering

7828-409: The latter, is usually determined by specific requirements of the sniper's role in a particular organization, with each design having advantages and disadvantages. For a given cartridge, a bolt-action rifle is cheaper to build and maintain, more reliable, and lighter, due to fewer moving parts in the mechanism. In addition, the absence of uncontrolled automatic cartridge case ejection helps avoid revealing

7931-457: The long-range destruction of explosive devices; these rifles may also be used against personnel. Anti-materiel rifles tend to be semi-automatic and of a larger caliber than other rifles, using cartridges such as the .50 BMG (12.7×99mm), 12.7×108mm , 14.5×114mm , and 20mm . These large cartridges are required to be able to fire projectiles containing payloads such as explosives, armor-piercing cores, incendiaries or combinations of these, such as

8034-836: The minimum distance for safety is much greater than the specified range for accuracy.) A firearm is a barreled ranged weapon that inflicts damage on targets by launching one or more projectiles driven by rapidly expanding high-pressure gas produced by exothermic combustion ( deflagration ) of a chemical propellant , historically black powder , now smokeless powder . In the military, firearms are categorized into heavy and light weapons regarding their portability by infantry . Light firearms are those that can be readily carried by individual foot soldier , though they might still require more than one individual ( crew-served ) to achieve optimal operational capacity. Heavy firearms are those that are too large and heavy to be transported on foot, or too unstable against recoil , and thus require

8137-448: The modern style of guerrilla warfare . The durability, accuracy and power of sniper rifles circa 2010 are beyond anything in use even ten years prior, and dwarf those of World War II sniper rifles. Modern sniper rifles are very reliable and are able to fire repeatedly without losing accuracy, whereas earlier sniper rifles were more liable to lose accuracy due to wear and tear . Sniper rifles continue to be adapted and improved upon, with

8240-512: The musket; both having single-shot , break-action , bolt-action , lever-action , pump-action , semi-automatic , and automatic variants; and both being popular with militaries, police, and civilians for largely the same reasons. However, unlike rifles, shotguns are less favored in combat roles due to their low accuracy and limited effectiveness in modern warfare , with combat shotguns often only used for breaching or close-quarters combat and sometimes limited to underbarrel attachments such as

8343-399: The notable exception of smoothbore shotguns ) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber (i.e. bore diameter). For pistols and rifles this is given in millimeters or inches (e.g. 7.62mm or .308 in.); in the case of shotguns, gauge or bore (e.g. 12 ga. or .410 bore.). They are also described by

8446-450: The point of impact. Stocks manufactured from polymers and metal alloys are less susceptible to point of impact shifting from environmental conditions. Sniper stocks are typically designed to avoid making contact with the barrel of the weapon to minimize the effects of environmental inconstancies. Modern sniper rifle stocks tend to be designed around a rigid chassis, offer user adjustability to allow shooters of various sizes and shapes to tailor

8549-509: The portable fire lance , operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon . The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant , but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with

8652-512: The projectile did not have to "bite" into the rifling grooves as with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield , which had shown weaknesses during the Crimean War . At trials in 1857, which tested the accuracy and range of both weapons, Whitworth's design outperformed the Enfield at a rate of about three to one. The Whitworth rifle was able to hit the target at

8755-734: The rear of the barrel, and are often loaded using magazines of varying capacities; revolvers , which have a number of firing chambers or "charge holes" in a revolving cylinder , each one loaded with a single cartridge or charge; and derringers , broadly defined as any handgun that is not a traditional pistol nor a revolver. There are various types of the aforementioned handguns designed for different mechanisms or purposes, such as single-shot , manual repeating , semi-automatic , or automatic pistols; single-action , double-action , or double-action/single-action revolvers; and small, compact handguns for concealed carry such as pocket pistols and " Saturday night specials ". Examples of pistols include

8858-523: The rifle's function and purpose as in semi-automatic rifles , automatic rifles and sniper rifles , to differences in the rifle's action as in single-shot , break-action , bolt-action , and lever-action rifles. Examples of rifles of various types include the Henry rifle , Winchester rifle , Lee–Enfield , Gewehr 98 , M1 Garand , MAS-36 rifle , AKM , Ruger 10/22 , Heckler & Koch G3 , Remington Model 700 , and Heckler & Koch HK417 . A shotgun

8961-434: The sacrifice of a small degree of accuracy. Military snipers and sharpshooters may also be required to carry their rifles and other equipment for long distances, making it important to minimize weight. Military organizations often operate under strict budget constraints, which influences the type and quality of sniper rifles they purchase. Sniper rifles built or modified for use in law enforcement are generally required to have

9064-510: The same purposes. However, some prefer battle rifles for their more powerful cartridge, despite the added recoil. Some designated marksman rifles are configured from battle rifles, such as the Mk 14 Enhanced Battle Rifle and United States Marine Corps Designated Marksman Rifle , both essentially heavily modified and modernized variants of the M14 rifle . Examples of rifles considered to be battle rifles include

9167-529: The scope above the barrel for optimal accuracy. During World War I, the accuracy of the sniper rifle was greatly improved. By the end of World War II, snipers were reported to provide "reasonable accuracy" over 600 m (656 yd) with anything over this range being unpredictable. It was during World War I and II that the word ‘sniper’ began to be used commonly, whereas previously those who were armed with sniper rifles were referred to as sharpshooters or marksmen. These marksmen, wielding sniper rifles such as

9270-596: The semi-automatic or burst fire of standard rifles. They are commonly associated with being belt-fed , though many machine guns are also fed by box, drum, pan, or hopper magazines. They generally have a high rate of fire and a large ammunition capacity, and are often used for suppressive fire to support infantry advances or defend positions from enemy assaults. Owing to their versatility and firepower, they are also commonly installed on military vehicles and military aircraft , either as main or ancillary weapons . Many machine guns are individual-served and can be operated by

9373-570: The shooter's position. Semi-automatic weapons can serve both as a battle rifle and sniper rifle, and allow for a greater rate (and hence volume) of fire. As such rifles may be modified service rifles, an additional benefit can be commonality of operation with the issued infantry rifle. A bolt action is most commonly used in both military and police roles due to its higher accuracy and ease of maintenance. Special forces operators tend to prefer semi-automatic rifles over bolt-action rifles for certain applications such as detonating unexploded ordnance from

9476-480: The single most important characteristic that sets a sniper rifle apart from other military or police small arms is the mounting of a telescopic sight , which is relatively easy to distinguish from smaller optical aiming devices found on some modern assault rifles and submachine guns (such as reflector sights ). The telescopic sights used on sniper rifles differ from other optical sights in that they offer much greater magnification (more than 4× and up to 40×) and have

9579-586: The size of carbines and short-barreled rifles, and use similar configurations. Many are designed to take as little space as possible for use in close-quarters or for easy storage in vehicles and cases. Some submachine guns are designed and configured similar to pistols even down to size, and are thus occasionally classed as machine pistols , even if they are not actually a handgun (i.e. designed to require two hands to use). Submachine guns are considered ideal for close-quarters combat and are cheap to mass-produce. They were very common in military service through much of

9682-477: The sling, keeping that arm still. Non-static weapon mounts , such as bipods , monopods , and shooting sticks , are also regularly used to aid and improve stability and reduce operator fatigue. Shooting bags are also commonly used to help stabilize the rifle or to provide an adjustable base. A military-issue battle rifle or assault rifle is usually capable of between 3–6 minute of angle (0.9–1.7 milliradian ) accuracy. A standard-issue military sniper rifle

9785-458: The sniper, can be exploited. The most popular military sniper rifles (in terms of numbers in service) are chambered for 7.62 mm (0.30 inch) caliber ammunition, such as 7.62×51mm and 7.62×54mm R . Since sniper rifles of this class must compete with several other types of military weapons with similar range, snipers invariably must employ skilled fieldcraft to conceal their position. The recent trend in specialized military sniper rifles

9888-437: The stock to their personal preferences, and modular attachment points to accommodate low-light and daylight aiming optics, laser designators, and other accessories without the need for custom-made mounting interface kits. An adjustable sling is often fitted on the rifle, used by the sniper to achieve better stability when standing, kneeling, or sitting. The sniper uses the sling to "lock in" by wrapping their non-firing arm into

9991-560: The support of a weapons platform (e.g. a fixed mount , wheeled carriage , vehicle , aircraft or water vessel ) to be tactically mobile or useful. The subset of light firearms that only use kinetic projectiles and are compact enough to be operated to full capacity by a single infantryman (individual-served) are also referred to as small arms . Such firearms include handguns such as pistols , revolvers , and derringers ; and long guns such as rifles (and their subtypes), shotguns , submachine guns , and machine guns . Among

10094-512: The telescopic sights attached to sniper rifles were too easily damaged and thus not well suited for military use. However, they soon realized that these telescopic sights could be improved and made sturdy enough to withstand a sniper rifle shot. Sniper rifles have continued to be used consistently throughout the later part of the 20th century in Korea, Vietnam and the Middle East as an integral part of

10197-456: The type of action employed (e.g. muzzleloader , breechloader , lever , bolt , pump , revolver , semi-automatic , fully automatic , etc.), together with the usual means of deportment (i.e. hand-held or mechanical mounting). Further classification may make reference to the type of barrel used (i.e. rifled ) and to the barrel length (e.g. 24 inches), to the firing mechanism (e.g. matchlock , wheellock , flintlock , or percussion lock ), to

10300-616: The works were reorganised as Maschinenbau Kiel . In 1955 the shipyard areas were bought by Howaldtswerke . This German corporation or company article is a stub . You can help Misplaced Pages by expanding it . Firearm A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions ). The first firearms originated in 10th-century China , when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make

10403-414: The world's arms manufacturers , the top firearms manufacturers are Browning , Remington , Colt , Ruger , Smith & Wesson , Savage , Mossberg (United States), Heckler & Koch , SIG Sauer , Walther (Germany), ČZUB (Czech Republic), Glock , Steyr Arms (Austria), FN Herstal (Belgium), Beretta (Italy), Norinco (China), Rostec , and Kalashnikov (Russia). Former top producers included

10506-485: The worldwide total of civilian-held firearms. This amounts to "120.5 firearms for every 100 residents". The world's armed forces control about 133 million (about 13 percent) of the global total of small arms, of which over 43 percent belong to two countries: the Russian Federation (30.3 million) and China (27.5 million). Law enforcement agencies control about 23 million (about 2 percent) of

10609-462: Was originally fixed and could not be adjusted, which therefore limited its range. By the 1870s, the perfection of breech loading magazine rifles led to sniper rifles having "effective accurate" ranges of up to a mile away from their target. During the Second Boer War , the latest breech-loading rifles with magazines and smokeless powder were used by both sides. The British were equipped with
