Illustration of forces in muzzle rise. Projectile and propellant gases act on barrel along barrel centerline A. Forces are resisted by shooter contact with gun at grips and stock B. Height difference between barrel centerline and average point of contact is height C. Forces A and B operating over moment arm / height C create torque or moment D, which rotates the firearm's muzzle up as ...
Its muzzle brake has three small rectangular ports on each side that serve to reduce muzzle rise, however their main purpose is to protect the muzzle from damage.

The AK-47 was designed to be a simple, reliable fully automatic rifle that could be manufactured quickly and cheaply, using mass production methods that were state of the art in the Soviet Union during the late 1940s. [41] The AK-47 uses a long-stroke gas system generally associated with high reliability in adverse conditions.
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.
Kalashnikov rifles (Russian: Автоматы Калашникова), also known as the AK platform, AK rifles or simply the AK, are a family of assault rifles based on Mikhail Kalashnikov's original design.
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 7.62×39mm (aka 7.62 Soviet, formerly .30 Russian Short) [5] round is a rimless bottlenecked intermediate cartridge of Soviet origin. The cartridge is widely used due to the global proliferation of the AK-47 rifle and related Kalashnikov rifles, the SKS semi automatic rifle, as well as the RPD and RPK light machine guns.
