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.

Firearms that are physically small, such as handguns, use a system of recoil referred to as short recoil. [1] [4] This is adequate for the smaller calibers. In large firearms such as the Browning M2HB .50 caliber machine gun a similar system called long recoil is used. The difference is how far the breech and barrel recoil together after a shot ...
Blish put this theory to use in a delayed-blowback breech mechanism. He developed a working model that used a simple wedge as the delay mechanism, and was eventually assigned U.S. patent 1,131,319 on March 9, 1915. Despite the patent and use of the system in the Thompson submachine gun, the Blish principle found little scientific backing. [1]

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 ...
An alternative design concept for recoil-operated firearms is the inertia operated system, the first practical use of it being the Sjögren shotgun, developed by Carl Axel Theodor Sjögren in the early 1900s, a Swedish engineer who was awarded a number of patents for his inertia operated design between 1900 and 1908 and sold about 5,000 ...
