Long recoil operation is found primarily in shotguns, particularly ones based on John Browning's Auto-5 action. In 1885 a locked breech, long recoil action was patented by the Britons Schlund and Arthur. [9] In a long recoil action, the barrel and bolt remain locked together during recoil, compressing the recoil springs.
The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber, and is commonly visible as a cylinder mounted parallel to ...
The recoil force only acts during the time that the ejecta are still in the barrel of the gun. The counter-recoil force is generally applied over a longer time period and adds forward momentum to the gun equal to the backward momentum supplied by the recoil force, in order to bring the gun to a halt.
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
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 ...
An M40 recoilless rifle on its M79 "wheelbarrow" tripod Diagram of the operation of a recoilless rifle using a vented case. A recoilless rifle (), recoilless launcher (), or simply recoilless gun, sometimes abbreviated to "RR" or "RCL" (for ReCoilLess) [1] is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant ...

The M1941 rifle used the energy from recoil to cycle the rifle. As the bullet and propellant gases move down the barrel, they impart force on the bolt head which is locked to the barrel. The barrel, together with the bolt, moves a short distance rearward until the bullet leaves the barrel and pressure in the bore drops to safe levels.
