This system had its origins in the late-war StG 45(M) assault rifle prototype. Roller-delayed blowback was first used in Mauser's Gerät 06H prototype. 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]

The Walther CCP is operated by a gas-delayed blowback system, using gas pressure from the ignited cartridge by directing it through a small port in the barrel in front of the chamber to slow down and delay the rearward motion of the slide. This design is nearly identical to the design of the Heckler & Koch P7. Walther calls this system Softcoil.
In 1885, one year after Maxim's first gas-operated patent, a British inventor called Richard Paulson, who a year before had patented a straight blowback-operated rifle and pistol, again, one year after Maxim’s first blowback patent, patented a gas piston-operated rifle and pistol which he claimed could be used with sliding, rotating or ...
The Steyr GB is a double-action 9×19mm Parabellum caliber, large-framed semi-automatic pistol employing a gas-delayed blowback action. As such the GB abbreviation stands for Gasbremse (gas brake). It was designed in 1968, intended as a replacement for older handguns in Austrian military service.
A schematic of the lever-delayed blowback mechanism used in the FAMAS assault rifle. 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 ...
Designed in 2006 and seeing limited production since 2009, the KRISS Vector uses an unconventional delayed blowback system combined with in-line design to reduce perceived recoil and muzzle climb, invented by French engineer Renaud Kerbrat. [5] The weapon is designed to accept extended Glock magazines and fires a variety of pistol cartridges.
A schematic of the P7's gas-delayed blowback system.. The P7 is a semi-automatic blowback-operated firearm. It features a unique gas-delayed blowback system modeled on the Swiss Pistole 47 W+F (Waffenfabrik Bern) prototype pistol [6] (and ultimately on the Barnitzke system first used in the Volkssturmgewehr 1-5), [7] which used gas pressures from the ignited cartridge and fed them through a ...
