In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle but subsequently failed to develop that idea further. [2] Between 1883 and 1885, Hiram Maxim filed several patents on blowback-, recoil-, and gas-operation. In 1885, one year after Maxim's first gas-operated patent, a British inventor called Richard ...
Roller-delayed blowback operation differs from roller-locked recoil operation as seen in the MG 42 and gas operated roller locked, as seen in the Gerät 03 and Gerät 06. [25] Unlike the MG 42, in roller-delayed blowback the barrel is fixed and does not recoil, and unlike the Gerät 03 and Gerät 06 and StG 44, roller-delayed blowback systems ...
Blow forward (left) vs. blowback (right) operation. The Mannlicher M1894 pistol, the first blow-forward firearm.. Blow forward is a firearm action where the propellant gas pressure and the friction of the bullet traveling down the bore drag the whole gun barrel forward to facilitate the opening of the breech.

Gas-operated reloading: A system of operation used to provide energy to operate autoloading firearms. Gatling gun: A hand-crank operated cannon named after its inventor, Richard Gatling. In modern usage, a Gatling often refers to a rotary machine gun. Gauge: The gauge of a firearm is a unit of measurement used to express the diameter of the barrel.
[7] [8] [9] Other non-gas-operated models included the Mannlicher Model 85, 91, 93, and 95 rifles. [10] The designs never proceeded past the conceptual/prototype stage due to issues inherent to the black powder used in their cartridges (based around the Austrian 11×58mmR M/77 ), such as insufficient velocity and excessive fouling .

The blowback operation is a system in which semi-automatic and fully automatic firearms operate through the energy created by combustion in the chamber and bore acting directly on the bolt face through the cartridge. In blowback operation the bolt is not locked to the chamber, relying only on spring pressure and inertia from the weight of the ...
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]
