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 Kord-12.7 mm heavy machine gun is a Russian design that entered service in 1998 [3] replacing the older NSV machine gun.Externally the weapon resembles the NSV; however, the internal mechanism has been extensively reworked, changing from a horizontally pivoting breech block to a rotating bolt design.

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 ...
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.
The M102 fires the same semi-fixed ammunition as the M101, but its longer barrel (32 calibres versus 22 calibres on M101) allows a slightly higher muzzle velocity and thus enhanced firing range. [1] A low silhouette made the new weapon a more difficult target for the enemy, an advantage that far outweighed the disadvantage of being somewhat ...
