Gas-operated
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle, but subsequently failed to develop that idea further. Between 1883 a ...

M1 Carbine
The M1 carbine (formally the United States Carbine, Caliber .30, M1) is a lightweight semi-automatic carbine that was a standard firearm for the U.S. military during World War II, the Korean War and the Vietnam War. The M1 carbine was produced in several variants and was widely used by paramilitary and police forces around the world, and also became a popular civilian firearm after World War II. The M2 carbine is the selective-fire version of the M1 carbine, capable of firing in both semi-automatic and full-automatic. The M3 carbine was an M2 carbine with an active infrared scope system. Despite having a similar name and physical outward appearance, the M1 carbine is not a carbine version of the M1 Garand rifle. On July 1, 1925, the U.S. Army began using the current naming convention where the "M" is the designation for "Model" and the number represents the sequential development of equipment and weapons. Therefore, the "M1 carbine" was the first carbine developed under this s ...

AK-47
The AK-47, officially known as the ''Avtomat Kalashnikova'' (; also known as the Kalashnikov or just AK), is a gas operated, gas-operated assault rifle that is chambered for the 7.62×39mm cartridge. Developed in the Soviet Union by Russian small-arms designer Mikhail Kalashnikov, it is the originating firearm of the Kalashnikov rifle, Kalashnikov (or "AK") family of rifles. After more than seven decades since its creation, the AK-47 model and its variants remain one of the most popular and widely used firearms in the world. The number "47" refers to the year the rifle was finished. Design work on the AK-47 began in 1945. It was presented for official military trials in 1947, and, in 1948, the fixed-Stock (gun), stock version was introduced into active service for selected units of the Soviet Army. In early 1949, the AK was officially accepted by the Soviet Armed Forces and used by the majority of the member states of the Warsaw Pact. The model and its variants owe their glob ...

M1895 Colt–Browning Machine Gun
The Colt–Browning M1895, nicknamed "potato digger" because of its unusual operating mechanism, is an air-cooled, belt-fed, gas-operated machine gun that fires from a closed bolt with a cyclic rate of 450 rounds per minute. Based on an 1889 design by John Browning and his brother Matthew S. Browning, it was the first successful gas-operated machine gun to enter service. Operating mechanism Filed for patent in 1892, the M1895's operating mechanism is one of John and Matthew S. Browning's early patents for automatic rifles; they had previously been working on lever-action rifles for Winchester such as the Winchester 1886. In a typical lever-action design, the operating lever lies under the rear of the gun, typically below the stock, and is hinged near the breech area. It is operated by rotating the lever down and forward, which causes the breechblock to slide rearward away from the barrel and eject the spent round. The potato digger mechanism, in effect, bears some similari ...

M1 Garand
The M1 Garand or M1 rifleOfficially designated as U.S. rifle, caliber .30, M1, later simply called Rifle, Caliber .30, M1, also called US Rifle, Cal. .30, M1 is a semi-automatic rifle that was the service rifle of the U.S Army during World War II and the Korean War. The rifle is chambered for the .30-06 Springfield cartridge and is named after its Canadian Americans, Canadian-American designer, John Garand. It was the first standard-issue autoloading rifle for the United States. By most accounts, the M1 rifle performed well. General George S. Patton called it "the greatest battle implement ever devised". The M1 replaced the bolt-action M1903 Springfield as the U.S.' service rifle in 1936, and was itself replaced by the selective fire, selective-fire M14 rifle on March 26, 1958. Pronunciation Sources differ on the pronunciation of the M1 Garand. Some, such as General Julian Hatcher, Julian Hatcher's ''The Book of the Garand'' (1948), give , identical to the pronunciation of Joh ...

Tavor
The IWI Tavor TAR-21 is an Israeli bullpup assault rifle chambered in 5.56×45mm NATO caliber with a selective fire system, selecting between semi-automatic mode and full automatic fire mode. The Tavor is designed and produced by Israel Weapon Industries (IWI). It is produced in two main variants: the TAR-21 and the CTAR-21. Built around a long-stroke piston system (as found in the M1 Garand and AK-47), the Tavor is designed to maximize reliability, durability, simplicity of design, and ease of maintenance, particularly under adverse or battlefield conditions. In 2009, the Tavor X95 (also known as the Micro Tavor or MTAR) was selected by the Israeli Defense Forces to gradually replace the M16 assault rifle and M4 carbine variants as the standard-issued weapon of the Israeli infantry by the end of 2018. The first X95 bullpup rifles were issued to infantry units in 2013. Both the TAR-21 and X95 are part of the Tavor family of rifles, along with the Tavor 7. In the beginning ...

Bren Light Machine Gun
The Bren gun was a series of light machine guns (LMG) made by Britain in the 1930s and used in various roles until 1992. While best known for its role as the British and Commonwealth forces' primary infantry LMG in World War II, it was also used in the Korean War and saw service throughout the latter half of the 20th century, including the 1982 Falklands War. Although fitted with a bipod, it could also be mounted on a tripod or be vehicle-mounted. The Bren gun was a licensed version of the Czechoslovak ZGB 33 light machine gun which, in turn, was a modified version of the ZB vz. 26, which British Army officials had tested during a firearms service competition in the 1930s. The later Bren gun featured a distinctive top-mounted curved box magazine, conical flash hider, and quick change barrel. The name ''Bren'' was derived from Brno, the Czechoslovak city in Moravia, where the Zb vz. 26 was designed (in the Zbrojovka Brno Factory) and Enfield, site of the British Royal Small A ...

Gewehr 41
The Gewehr 41 (German for: rifle 41), commonly known as the G41(W) or G41(M), denoting the manufacturer (Walther or Mauser), are two distinct and different battle rifles manufactured and used by Nazi Germany during World War II. They were largely superseded by the Gewehr 43, which was derived from the G41(W), but with an improved gas system and other detail changes. Background By 1940, it became apparent that some form of a semi-automatic rifle with a higher rate of fire than existing bolt-action rifle models were necessary to improve the infantry's combat efficiency. The Army issued a specification to various manufacturers, and Mauser and Walther submitted prototypes that were very similar. However, some restrictions were placed upon the design: * no holes were to be bored into the barrel for tapping gas for the loading mechanism; * the rifles were not to have any moving parts on the surface; * and in case the auto-loading mechanism failed, a bolt action was to be included. ...

Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...
