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.
This is not adequate with higher velocity and higher energy cartridges. Rifles and most handguns use locked breech designs to control recoil safely. The amount of mass of the components, the strength of springs, [6] and the distance the barrel and slide are allowed to recoil is carefully calculated and tested to ensure safety.
The rearward motion of the slide is initiated by the force of firing, and continues using the slide's inertia. While the slide moves rearwards, a spring, called the recoil spring, is compressed, absorbing the energy of the slide while slowing it down. Approximately 50% of the momentum imparted by the bullet and gas is converted into kinetic ...
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 ...
This means that the G47 slide and barrel can be put on a G19 frame to give the G19 a longer slide, barrel, and sight radius (the equivalent of a Glock 49), and the G19 slide and barrel can be put on a G47 frame to create a pistol that functions like a Glock 45. The G47 recoil spring assembly is the same as for the G19.
In a soft-recoil system, the spring (or air cylinder) that returns the barrel to the forward position starts out in a nearly fully compressed state, then the gun's barrel is released free to fly forward in the moment before firing; the charge is then ignited just as the barrel reaches the fully forward position. Since the barrel is still moving ...
Animation of the Vickers muzzle booster operation, showing the expanding gases pushing the barrel to the rear relative to the cooling jacket. A Vickers-type muzzle (or recoil) booster, the "typical" type, consists of two parts: a flared "cup" on the muzzle of the barrel, and a perforated tube around the end of the muzzle, attached to the main body of the weapon.
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.
