84-633: The SAR 21 (" Singapore Assault Rifle - 21st Century ") is a bullpup assault rifle designed and manufactured in Singapore , chambered for the 5.56x45mm cartridge. First revealed and subsequently adopted by the Singapore Armed Forces (SAF) as its standard service weapon in 1999, it was designed and developed over a four-year period to replace the locally license-built M16S1 by the Ministry of Defence (MINDEF) , Singapore Army and
168-471: A long stroke gas system and a two-lug Stoner-style bolt, boasting high reliability. The translucent magazine allows precise assessment of its current ammo load. The SAR 21 has a built-in Laser Aiming Device (powered by a single "AA-size" battery ) which has a 5 position switch that emits a visible or infrared beam at high or low power. It can be set to a steady beam or a momentary beam that
252-568: 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
336-445: 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
420-666: 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
504-423: 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
588-625: 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
672-452: 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
756-695: A gas-powered rifle with a locking system based on the Sturmgewehr. The design used steel pressings which were difficult to obtain, and so was scrapped. The result of the Polish design team's efforts was the EM-2 , which broke significant ground. The EM-2 contained some similarities to the Soviet AK-47 , although Januszewski had never seen the Soviet rifle. The first significant bullpup assault rifle came from
840-793: 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
924-527: A patent was filed with the United States Patent and Trademark Office by Tuck Wah Chee and Felix Tsai with the patent number 6,481,144 B1. MINDEF officials, after consultations with the SAF, decided against buying weapons off the shelf as it would require soldiers to adjust to the new weapon, choosing instead to develop a weapon, designed and made specifically for ease of use by conscript soldiers of

#17328024677771008-469: 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
1092-500: A submachine gun, but shorter than that of conventional semi-automatic or bolt-action rifles. The bullpup design was deemed necessary to retain the accuracy at range while reducing overall length. The EM-2 was adopted by the UK in 1951 as the world's first (limited) service bullpup rifle, but was promptly displaced by the adoption of the 7.62×51mm NATO (0.308 in) cartridge, to which the EM-2
1176-410: 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
1260-551: 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
1344-616: 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
1428-417: 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
1512-547: Is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity , range, and ballistic effectiveness. The bullpup concept was first tested militarily in 1901 with the British Thorneycroft carbine , but it was not until the Cold War that more successful designs and improvements led to wider adoption. In 1977,
1596-540: Is factory-zeroed, and requires minimal further zeroing to suit different users, shortening non-training range time. Early users of the weapon in the Singapore Armed Forces experienced many problems due to their unfamiliarity with the bullpup design. Their criticisms (usually compared to the M16S1 rifles they were trained with) include: Some of these criticisms were addressed with design modifications to
1680-566: Is held in the collection of the British National Rifle Association . One of the earliest repeating bullpup designs was patented by William Joseph Curtis in 1866. The concept was later used in bolt-action rifles such as the Thorneycroft carbine of 1901, although the increased distance from hand grip to bolt handle meant the decreased length had to be weighed against the increased time required to fire. It
1764-666: Is in increasing demand in other countries, notably India. The Tavor shares many similarities with the SAR 21 and the South African Vektor CR-21 . The Chinese People's Liberation Army adopted the Type 95 gun family in 1997, a family of bullpup firearms sharing a common receiver design, which includes the QBZ-95 standard rifle, a carbine and light support weapon variants. The Islamic Republic of Iran Army has adopted

#17328024677771848-544: 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
1932-473: 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
2016-427: Is triggered by a pressure switch activated with the user's left thumb. The rifle incorporates various patented safety features, such as a Kevlar cheek plate and a high pressure vent that protects the shooter in the event of a chamber explosion or catastrophic failure. The integral 1.5x optical scope that is built into its carrying handle aids in target acquisition, particularly under low light conditions. The scope
2100-527: 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
2184-585: The Austrian Army became the first military force in the world to adopt a bullpup rifle, the Steyr AUG , as a principal combat weapon . Since then the militaries in many countries have followed suit with other bullpup designs, such as the Chinese QBZ-95 , Israeli IWI Tavor , French FAMAS and British SA80 . The origin of term "bullpup" for this configuration has long been unclear. In 1957,
2268-590: 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
2352-610: 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

Having learned from extensive combat experience, Israel Military Industries developed a bullpup rifle: the Tavor TAR-21 . The Tavor is light, accurate, fully ambidextrous and reliable (designed to stringent reliability standards to avoid malfunctioning in desert conditions), and
2604-514: 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

As Januszewski was developing a new rifle, the "Ideal Calibre Board" was searching for a replacement for the .303 cartridge. The Board decided on an optimal 7 mm cartridge on which Januszewski and the two teams working at Enfield had to base their designs. One design team led by Stanley Thorpe produced
3612-865: 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
3696-426: 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
3780-582: The British programme to replace the service pistols, sub-machine guns, and rifles. In the two forms of the EM-1 and the EM-2, the new rifle concept was born as a result of the experience with small arms that was gained during the Second World War. It was obvious that modern warfare would require the infantry to be armed with a light, selective fire weapon, with effective range much longer than that of
3864-470: The German Sturmgewehr 44 assault rifle , which offered a compromise between bolt-action rifles and submachine guns. Among them was Kazimierz Januszewski (also known as Stefan Janson), a Polish engineer who had worked at the Polish national arsenal during the 1930s. After being mobilized during World War II he escaped German and Soviet forces and made his way to England, where he was a part of

In 2009, criminal charges were filed against former Indian Ordnance Factory Board director Sudipta Ghosh for corruption, among the allegations were an improper partnership with STK over supplying Indian law enforcement with the SAR 21 Modular Mounting System. STK and several foreign firms involved were blacklisted by
4116-568: The Steyr AUG showed clearly the potential of the bullpup layout. The arrival of the FAMAS in 1978, and its adoption by France emphasized the slide from traditional to bullpup layouts within rifle designs. The British resumed their bullpup experiments with the L85 , which entered service in 1985. After persistent reliability problems, it was redesigned by the then British-owned Heckler & Koch into

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;

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;

The Kevlar plating on the left side of the weapon butt (where a right-handed user's face would typically be) is effective in protecting the user from any internal chamber explosion by directing the resulting force to the right. However, that resultant force would also seriously injure anyone on the right side of the weapon. In

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

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
5880-734: 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
5964-527: 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
6048-516: 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
6132-596: 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
6216-586: 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
6300-560: 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
6384-512: The trigger for the gun to be classified as a bullpup), but in some designs such as the Heckler & Koch G11 , FN P90 and Neostead , the magazine can extend forward beyond the trigger. The earliest bullpup firearm known is a heavy bench-rest target rifle made circa 1860 for a Professor Richard Potter by Riviere of London. It weighs more than 6 kg (13 lb 4 oz) and features an octagonal barrel of approximately 20 bore (0.60 in) in calibre, with two-groove Brunswick rifling . It
6468-431: The trigger guard. The position of the fire selector button (SEMI or AUTO) on the stock may also be adjusted. The on/off switch for the laser aiming device is located on the left handguard; when holding the weapon at ready, the left thumb rests naturally on it. With sluggish operation due to fouling, the gas regulator setting may be adjusted by turning it with a coin, screwdriver, or any other thin flat object. Alternatively,
6552-456: 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
6636-443: The word to describe dogs has since fallen out of use. The bullpup design places the gun's action mechanism and magazine behind the trigger, and the receiver functionally serves as the buttstock with usually only a thin endplate, making the gun more of a "stockless" weapon from a pure technical sense. The magazine is also inserted behind the trigger group (technically it only needs the magazine's feeding slot to be located behind
6720-567: The word was reported to denote a target pistol, particularly one with a fancy stock. British firearm expert Jonathan Ferguson researched the origin of the term in 2019–2020. He found early references in 1930s firearm magazines implying that "bullpup" is derived from an analogy of such rifles to bulldog puppies (colloquially called "bullpups" in England during the late 19th and the early 20th century), which were considered "squat, ugly but still aggressive and powerful". The original meaning of
6804-414: 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
6888-493: 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
6972-574: Was not easily adapted. The decision was rescinded and a variant of the more conventional FN FAL was adopted in its place. A 7.62×39mm M43 calibre experimental assault rifle was developed by German A. Korobov in the Soviet Union around 1945, and a further development, the TKB-408 was entered for the 1946–47 assault rifle trials by the Soviet Army, although it was rejected in favour of
7056-644: Was used in semi-automatic firearms in 1918 (6.5 mm French Faucon-Meunier semi-automatic rifle developed by Lt. Col. Armand-Frédéric Faucon), then in 1936 a bullpup machine pistol was patented by the Frenchman Henri Delacre . The first bullpup design used in combat was the PzB M.SS.41 anti-tank rifle during World War II. It was a Czech weapon used by the SS , produced under German occupation. After World War II, Western engineers drew inspiration from
