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.
20 lead balls of the diameter of a 20-gauge shotgun bore weigh one pound, while just 12 lead balls of the diameter of a 12-gauge shotgun bore equals the same weight. [2] A 20-gauge shotgun is more suitable for hunting certain types of game or for some hunters because it may have less felt recoil than an identical shotgun in a larger gauge, [5 ...
The weapon was used heavily by members of the Special Air Service in the Malayan Emergency, who found the semi-automatic shotgun perfect for close quarter jungle fighting. British troops utilized the unaltered Browning Auto-5 Sporter with a 28 inch barrel, supplemented by Remington 870-R slide action shotguns with 20 inch barrels. The British ...
For a gun firing under free-recoil conditions, the force on the gun may not only force the gun backwards, but may also cause it to rotate about its center of mass or recoil mount. This is particularly true of older firearms, such as the classic Kentucky rifle , where the butt stock angles down significantly lower than the barrel, providing a ...
The Model 11-48 is a long-recoil operated semi-automatic shotgun based on the Model 11, itself based on an 1898 design by John Browning. Shells are stored in a tubular magazine under the barrel . When a chambered shell is fired, the barrel and bolt recoiling together (for a distance greater than the shell length) re-cock the hammer , eject the ...
The barrel seal activator is meant to be removed when using 3 + 1 ⁄ 2-inch or 3-inch shells, and installed when using shorter shells. [1] Some Model 11-87s have interchangeable screw-in chokes; other barrels are available with fixed chokes. Barrels are not interchangeable between the Model 1100 and Model 11-87. [1]
The shotgun is multicharged, with a tubular underbarrel magazine of 3-cartridge capacity. Reloading is provided with a removable fore-end. The presence of the special barrel rear projection on the frame combined with the rear sight gives the possibility of mounting an optical sight. The shotgun is intended for the amateur hunting with shot ...
The minimum barrel length for shotguns in most of the U.S. is 18 inches (460 mm), and this barrel length (sometimes 18.5–20 in (470–510 mm) to increase magazine capacity and/or ensure the gun is legal regardless of measuring differences [3]) is the primary choice for riot shotguns. The shorter barrel makes the weapon easier to maneuver ...
