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 7.5 cm KwK 42 L/70 (from 7.5 cm Kampfwagenkanone 42 L/70) was a 7.5 cm calibre German tank gun used on German armoured fighting vehicles in the Second World War.The gun was the armament of the Panther medium tank and two variants of the Jagdpanzer IV self-propelled anti-tank gun.
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.
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.
The ability of the .300 Winchester Magnum chambering to obtain fairly high muzzle velocities, combined with relatively heavy and long very-low-drag bullets, significantly enhance the hit probability at longer ranges and hence the effective range compared to the 7.62×51mm NATO cartridge. The AWM chambered for the .300 is fitted with a fluted ...
The 8.8 cm KwK 36 was derived from the 8.8 cm Flak 36 anti-aircraft gun by adapting/modifying it to the limited space available in tank turrets. Parts of the KwK 36 were built to practically the same design as the 75-millimetre (3.0 in) and 50-millimetre (2.0 in) guns already used in German tanks.
The 7.5 cm KwK 40 (7.5 cm Kampfwagenkanone [a] 40) was a German 75 mm Second World War era vehicle-mounted gun, used as the primary armament of the German Panzer IV (F2 model onwards) medium tank and the Sturmgeschütz III (F model onwards) and Sturmgeschütz IV assault guns which were used as tank destroyers.
M114S − Israeli modernization package by Soltam Systems, the M114S features a 155 mm 33 caliber barrel, allowing a standard 155 mm M107 HE projectile to be fired to a maximum distance of 20,000 yards (18,300 m); a muzzle brake in the barrel, a pneumatic ramming system for the loader, improved mounts and fixtures, and an optional telescopic ...
