The AS-90 ("Artillery System for the 1990s"), known officially as Gun Equipment 155 mm L131, is an armoured self-propelled artillery used by the British Army.. It can fire standard charges up to 24.7 km (15.3 mi) using 39-calibre long barrel and 30 km (19 mi) with 52-calibre long barrel. [2]
Block diagram of long recoil operation cycle. 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 ...
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 average recoil force of the GAU-8/A is 10,000 pounds-force (45 kN), [5] [21] which is slightly more than the output of each of the A-10's two TF34 engines of 9,065 lbf (40.3 kN). [22] While this recoil force is significant, in practice a cannon-fire burst slows the aircraft by only a few miles per hour in level flight. [20]

The Humvee armament kit version fires at 1,300 rounds per minute. The average recoil force when firing is 382 lb/ft, 495 lb/ft or 629 lb/ft depending on firing rate. In January 2012, General Dynamics announced they would be delivering a new version designated GAU-19/B.
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.
Despite having a vertical magazine well (designed to accept 32-round staggered-feed direct copy of UZI magazine, rather than original single-feed Sten-type magazine), analogies with the Sten include a striking resemblance in the barrel assembly and in the bolt and recoil spring. In addition, this gun also fires from an open bolt, and is further ...
