In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder. [3]
The RAK is a selective-fire straight blowback–operated machine pistol, fired from the open bolt position. [4] Unlike most submachine guns firing from an open bolt, the PM-63 has a reciprocating external breech bolt, also known as a slide. The slide is part of the fire rate-reducing device.
Schematic of an Advanced Primer Ignition blowback operation that works in a similar way to slamfire by striking the cartridge as its moving forward before it is fully chambered. A slamfire is a discharge of a firearm occurring as a cartridge is being loaded into the chamber .
The recoil operation is a type of locked-breech action used in semi-automatic and fully automatic firearms. It also uses energy from the combustion in the chamber acting directly on the bolt through the cartridge head, but in this case the firearm has a reciprocating barrel and breech assembly, combined with a bolt that locks to the breech.
The Colt 9mm SMG is a closed bolt, blowback operated SMG, rather than the conventional direct impingement gas operation of the standard 5.56×45mm M16 type rifle. [6] As a closed bolt weapon, the Colt SMG is inherently more accurate than open bolt weapons such as the Israeli UZI. [7] The overall aesthetics are identical to most M16 type rifles.
Hi-Point's handguns use a blowback design similar to that used in the Walther PPK and Russian Makarov PM. In blowback weapons the mass of the slide and bolt absorbs the rearward force generated by the propulsion of the bullet. As the pressure drops to a safe level, the slide moves back (along with the bolt), an extractor hooks the empty casing ...
The Steyr GB is a semi-automatic, blowback-operated firearm. It features a unique gas-delayed blowback system based on the Barnitzke system, first used in the Volkssturmgewehr 1-5, [5] and subsequently in the Swiss Pistole 47 W+F (Waffenfabrik Bern) prototype pistol. [6]
The TAC-1 is an open bolt, blowback-operated firearm that uses a screw-delayed blowback operation that was first used on Mikhail Kalashnikov's submachine gun prototype. The weapon has a grip safety as well as a safety lever on the left side of the receiver, over the pistol grip.
