Blowback (firearms)
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APT Assault Rifle
Project Abakan was a Soviet/Russian advanced assault rifle program in rival to the US Advanced Combat Rifle that took place between 1980 and 1994. History The 1960s ushered a new generation of assault rifles with the introduction of smaller calibers. U.S. military analysis of combat during the Second World War showed that a greater volume of fire at shorter ranges was more significant than long range accuracy. They decided that a smaller caliber would be more effective in most conditions, because the soldier could carry more ammunition. In 1963, United States adopted the M16 Rifle and the smaller 5.56×45mm cartridge to replace the M14 Rifle and larger 7.62×51mm. In 1980, NATO adopted the 5.56mm as the standard issue rifle cartridge. In 1974, the Soviet Army also replaced the AKM with the AK-74 assault rifle chambered for the new smaller 5.45×39mm caliber. In spite of the smaller caliber and many other improvements the AK-74 failed to overcome the major shortcoming of its pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oerlikon SSG36
The Oerlikon SSG36 is an anti-tank rifle of Swiss origin. Overview The Oerlikon SSG36 anti-tank rifle demonstrated, that it was possible to build a successful straight blowback rifle up to 20 mm caliber shooting at 750 m/s (2460 ft/s) velocity. The SSG36 used a Becker principle of bolt head following the rebated rim cartridge base deep into the chamber. After firing, the case and the bolt could safely back off from the chamber without immediately exposing the base to explode under remaining chamber pressure. The bolt is shown under the barrel with cartridge attached to the protruding bolt head. The blowback action Oerlikon SSG36 has a deep chamber in which the cartridge totally sinks along with the bolt head. The massive recoil of the 20 mm cartridge was quite effectively tamed by the straight blowback operation and the mass of the bolt creating much less vigorous kick than regular delayed blowback actions. Service Some numbers were delivered to Bolivia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solothurn S-18/100
The Solothurn S-18/100 20 mm anti-tank cannon was a German and Swiss anti-tank rifle used during the Second World War. It had a semi-automatic action in a bullpup configuration. As a result of its large, powerful ammunition, the gun had a tremendous recoil, and its size made portability difficult. The feed was either from a five or (more usually) ten-round magazine that was attached horizontally to the left side of the gun. The gun used 20×105mm belted-case ammunition which it shared with the S 18-350 aircraft cannon that was developed from the rifle. A Finnish source gives armour penetration of the gun (probably achieved with the Hungarian APHE-T round, since it was the only type used in Finland) as 20mm at a 60-degree angle at 100-metre distance, decreasing to 16mm at 500 metres. A variant of this design, the Solothurn-Arsenal, was manufactured without license in Estonia before WW2; however only 20 were produced prior to Soviet occupation. In March 1940, with funds col ...

Heckler & Koch GMG
The GMG (''Granatmaschinengewehr'' or "grenade machine gun") is an automatic grenade launcher developed by Heckler & Koch for the German Army. It is also often referred to as GMW or GraMaWa (''Granatmaschinenwaffe''). Design details The GMG fires 40 mm grenades at a rate of about 340 rounds per minute. It is belt-fed, and can be loaded from either side, making it easy to mount on most platforms. With a variety of day and night sights available, the GMG can be used for most medium range infantry support situations. The weapon is 1.09 m long and has a 415 mm rifled barrel; the ammunition box has dimensions of 470 × 160 × 250 mm. The gun cycles on a recoil-operated blow-back basis. It weighs 29 kg; the tripod is an additional 11 kg. Testing and operation The HK GMG was tested in the Yuma desert in Arizona in 1997 in order to compete for future United States contracts. Users *: 304 ordered. Designated as the C16 Close Area Suppression Weapon (CASW ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40x53mm 40 mm grenade (also styled 40mm grenade) is a generic class-name for grenade launcher ammunition (subsonic shells) in caliber. The generic name stems from the fact that several countries have developed or adopted grenade launchers in 40 mm caliber. This is a general collection of the world's many different "40 mm grenades". NATO NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers. 40×46 mm LV (40 mm low velocity) ''40×46 mm LV'' (''low velocity'') is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, and Heckler & Koch AG36. The propellant has low pressure and gives the projectile an average velocity of depending |
