IMBEL MD2
The IMBEL MD series (MD-1, MD-2, MD-3 and the recent MD-4) of assault rifles are the standard-issue rifles of the Brazilian Army. History These rifles are manufactured by IMBEL (''Indústria de Material Bélico do Brasil'') and are based on the 7.62mm NATO FN FAL, which was previously manufactured by IMBEL for many years under licence as the Brazilian Army's standard service rifle. In following the trend to adopt the 5.56×45mm NATO round, IMBEL started experimenting with 5.56mm versions of the FN FAL in the early 1980s. The first prototype, the MD-1, appeared in around 1983. Further development resulted in the MD-2 and MD-3 series, which still closely resemble their FAL parent. Design The MD-2 and MD-3 rifles are the result of redesigning the FN FAL to use the 5.56×45mm NATO round in place of the FAL's 7.62mm NATO chambering. The MD-2/MD-3 series externally resembles a short-barrelled FAL, but with an M16 magazine. Early MD-1 prototypes retained the FAL-type tilting bol ...

STANAG
In NATO, a standardization agreement (STANAG, redundantly: STANAG agreement) defines processes, procedures, terms, and conditions for common military or technical procedures or equipment between the member countries of the alliance. Each NATO state ratifies a STANAG and implements it within its own military. The purpose is to provide common operational and administrative procedures and logistics, so one member nation's military may use the stores and support of another member's military. STANAGs also form the basis for technical interoperability between a wide variety of communication and information systems (CIS) essential for NATO and Allied operations. The Allied Data Publication 34 (ADatP-34) NATO Interoperability Standards and Profiles which is covered by STANAG 5524, maintains a catalogue of relevant information and communication technology standards. STANAGs are published in English and French, the two official languages of NATO, by the NATO Standardization Office in Bru ...

Magazine (firearm)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-autom ...

M16 Rifle
The M16 rifle (officially designated Rifle, Caliber 5.56 mm, M16) is a family of military rifles adapted from the ArmaLite AR-15 rifle for the United States military. The original M16 rifle was a 5.56×45mm automatic rifle with a 20-round magazine. In 1964, the M16 entered US military service and the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the US military's standard service rifle.Urdang, p. 801. The M16A1 incorporated numerous modifications including a bolt-assist, chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider. In 1983, the US Marine Corps adopted the M16A2 rifle and the US Army adopted it in 1986. The M16A2 fires the improved 5.56×45mm (M855/SS109) cartridge and has a newer adjustable rear sight, case deflector, heavy barrel, improved handguard, pistol grip and buttstock, as well as a semi-auto and three-round burst fire sele ...

FN FAL
The FAL (a French acronym for (English: "Light Automatic Rifle")), is a battle rifle designed in Belgium by Dieudonné Saive and manufactured by FN Herstal (simply known as FN). During the Cold War the FAL was adopted by many countries of the North Atlantic Treaty Organization (NATO), with the notable exception of the United States. It is one of the most widely used rifles in history, having been used by more than 90 countries.Hogg, Ian (2002). ''Jane's Guns Recognition Guide''. Jane's Information Group. . It is chambered in 7.62×51mm NATO (although originally designed for the intermediate .280 British). The British Commonwealth variant of the FAL was redesigned from FN's metrical FAL into British imperial units and was produced under licence as the L1A1 Self-Loading Rifle. History In 1946, the first FAL prototype was completed. It was designed to fire the intermediate 7.92×33mm Kurz cartridge developed and used by the forces of Germany during World War II with the ...

Rotating Bolt
Rotating bolt is a method of locking the breech (or rear barrel) of a firearm closed for firing. Johann Nicolaus von Dreyse developed the first rotating bolt firearm, the "Dreyse needle gun", in 1836. The Dreyse locked using the bolt handle rather than lugs on the bolt head like the Mauser M 98 or M16. The first rotating bolt rifle with two lugs on the bolt head was the Lebel Model 1886 rifle. The concept has been implemented on most firearms chambered for high powered cartridges since the 20th century. Design Ferdinand Ritter von Mannlicher, who had earlier developed a non-rotating bolt straight-pull rifle, developed the Steyr-Mannlicher M1895, a straight-pull rifle with a rotating bolt, which was issued to the Austro-Hungarian Army. Mannlicher then developed the M1893 auto rifle which had a screw delayed bolt and later the Mannlicher M1900 operated by a gas piston. This was an inspiration for later gas operated, semi-automatic and selective fire firearms (such as the M1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Stock (firearm)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
