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.
The barrel construction resulted in a very high muzzle velocity - up to 1,400 m/s. The bore was fitted with a muzzle brake . The horizontal sliding breech block was "quarter-automatic": it closed automatically once a shell was loaded, but unlike semi-automatic guns, the fired shell casing had to be manually ejected by opening the breech block.
For a typical .408 CheyTac chambered gun, shooting 27.15 gram (419 gr) Lost River Ballistic Technologies bullets (claimed G1 BC = 0.940) at 884 m/s (2900 ft/s) muzzle velocity, the supersonic range would be 1,930 m (2,110 yd) under International Standard Atmosphere sea level conditions (air density ρ = 1.225 kg/m 3).
The muzzle energy of the .950 JDJ is comparable to the kinetic energy of a 2,800 pounds (1,300 kilograms) automobile traveling at 20 miles per hour (32 kilometres per hour). In a 110 lb (50 kg) rifle, this will develop well over 200 foot-pounds force (270 joules) of free recoil energy.
These factors, along with Taylor’s dismissal of muzzle energy, allow many obsolete low powered large bore cartridges such as the .577/450 Martini-Henry and the .45-70 Government to have as much as twice the TKOF than the smaller bore general purpose hunting cartridges such as the .303 British and the .30-06 Springfield. For these reasons the ...
The felt recoil of a normal handgun in .38 Super is similar to the .45 ACP, but the higher pressure in the .38 Super provides more gas pressure for muzzle brakes. The .38 Super caliber became popular in the early 1980s, and has continued to be popular in the open division after its introduction in the 1993 season.
The operating mechanism does not require a gas expansion chamber at the muzzle, as in the AKS-74U to ensure reliable functioning, but does use a specially designed muzzle brake. The AMD-65, along with the earlier AKM-63, have been largely replaced in Hungarian military service by the AK-63, a more traditional AKM copy with a lower manufacturing ...
In 1944, a much cheaper muzzle brake patterned after the Polish Wz. 35 anti-tank rifle was introduced instead of the complicated early design. [23] After 1945, the DShK was exported widely to other countries in the Eastern Bloc. [16] In 1946, an improved variant was produced, with a revised muzzle and feeding system.
