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 op ...

Atchisson Assault Shotgun
The AA-12 (Auto Assault - 12), originally designed and known as the Atchisson Assault Shotgun, is a fully automatic combat shotgun developed in 1972 by Maxwell Atchisson. However, the original development by Atchisson seems to have produced only a few guns at prototype-level, with the development that ultimately led to the gun entering the market being done later by Military Police Systems, Inc. The most prominent feature is reduced recoil. The 2005 version was developed 19 years after the patent was sold to Military Police Systems, Inc. The original design later led to the development of several comparable firearms of such utility, including the USAS-12 combat shotgun. The shotgun utilizes fully automatic blowback action as its primary and only mode of fire. However, the relatively low cyclic rate of fire of around 300 rounds per minute enables the shooter to fire individual rounds through the use of short trigger pulls. It is fed from either an 8-round box magazine or 20-round ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9×19mm Parabellum
The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a Rim (firearms)#Rimless, rimless, Centerfire ammunition, centerfire, tapered cartridge (firearms), firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost, adequate stopping power and extensive availability. Since the cartridge was designed for the Luger pistol, Luger semi-automatic pistol, it has been given the designation of ''9mm Luger'' by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm [Parabellum]" and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

TZ-45
The TZ-45 was an Italian blowback-operated submachine gun produced between 1944 and 1945, with an estimated 6,000 made. History The TZ-45 submachine gun was designed by two Italians; Tonon, a lieutenant colonel in the National Republican Army whose first name remains unknown and Aldo Zorzoli, a gunsmith, and was produced by the Giandoso company. The vast majority of the estimated 6000 TZ 45s produced were issued to R.S.I. (Repubblica Sociale Italiana) units fighting against Italian partisan forces during the civil war in Northern Italy (1944–45). A few TZ-45 were possibly used by the Wehrmacht forces engaged in similar operations. After the war, the remaining guns were given to the military of the British and the American forces where they were evaluated. The general opinion was unfavorable due to the style of manufacturing and finish. The projects and manufacturing rights for the gun were later sold to the Burmese army where it was manufactured as the BA-52 and colloquia ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

40x53mm
This is a general collection of the world's many types of ammunition for grenade launchers in caliber. Several countries have developed or adopted grenade launchers in 40 mm caliber. 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, Heckler & Koch AG36 and M320 Grenade Launcher Module. The propellant has low pressure and gives the projectile an average velocity of depending on the ammunition type. 40 mm low-velocity ammunition types (NATO) Besides combat ammo there also exists crowd control am ...
