AK-74M (read me setting) Main differences from its predecessor: a new cartridge of caliber 5.45x39 mm (instead of 7.62x39 mm), which has a flatter bullet trajectory, which led to an increase in the direct shot range by 100 meters, and is also lighter (weight savings of 1.4 kg with a wearable ammunition load of 8 magazines) ; a new muzzle brake-compensator, which serves to increase the accuracy of the battle and reduce the recoil energy; shop made of light and durable plastic. For assault rifles produced in 1974 - 1986, the stock and forearm are made of wood. Since 1986, they began to be made of black plastic. Longitudinal grooves were made on the wooden butt on both sides to lighten the overall weight of the machine. They continue to be made on a plastic butt. Envelope from ArmA 2
