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 ...
Diagram of long-stroke gas operation system Long stroke gas piston, from an AK-74. With a long-stroke system, the piston is mechanically fixed to the bolt group and moves through the entire operating cycle. This system is used in weapons such as the Bren light machine gun, AK-47, Tavor, FN Minimi, FN MAG, FN FNC, and M1 Garand.
These are often called supplemental chambers or cartridge adapters, and the entire supplemental chamber is treated like a cartridge, being loaded and ejected as a unit with the smaller cartridge. Since the barrel of the firearm is used, the caliber of the cartridges must match. The most commonly encountered supplemental chambers are for .30 ...
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]
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.
Each barrel fires once per revolution at about the same 4 o'clock position. The barrels, a carrier and a lock cylinder were separate and all mounted on a solid plate, mounted on an oblong fixed frame. Manually turning the crank rotated the shaft. The carrier was grooved and the lock cylinder was drilled with holes corresponding to the barrels.
Attaching the barrel to the receiver using a barrel nut and a barrel with a shoulder is an alternative to action threads, which has been used in firearms such as the Sten gun and AR-15. Hand tools Quick barrel change systems is an increasingly popular alternative, as seen in for example SIG Sauer 200 STR, Roessler Titan or Blaser R8.
The simplest form of recoil buffer is made from a resilient and deformable material (leather, rubber, polymer e.g. a rubber butt pad on a shotgun). [1] A second way of producing a recoil buffer is to insert a spring into the recoil train—the path/part(s) generating recoil impulse.
