The RPK (Ruchnoy Pulemyot Kalashnikova, Russian: Ручной пулемёт Калашникова or "Kalashnikov hand-held machine gun") is a 7.62x39mm light machine gun of Soviet design, developed by Mikhail Kalashnikov in the late 1950s, parallel with the AKM assault rifle. It was created as part of a program designed to standardize the small arms inventory of the Red Army, where it replaced the 7.62x39mm RPD light machine gun. The RPK continues to be used by the armed forces of countries of the former Soviet Union and certain African and Asian nations. The RPK was also manufactured in Bulgaria, Poland, and Romania.
Most notably, the RPK has a heavier and longer barrel than an AKM. This allows the RPK to fire for extended periods of time without major loss in accuracy due to the barrel heating up. The chrome-lined barrel is permanently fixed to the receiver, and cannot be replaced in the field. It is fitted with a new front sight base, gas block (lacks the bayonet lug) and an under-barrel cleaning rod guide. The barrel also features a folding bipod, mounted near the muzzle, and a front sight base with a lug that limits the bipod's rotation around the axis of barrel. The barrel's muzzle is threaded, enabling the use of muzzle devices such as flash hiders, compensators, and blank-firing adapters. When a muzzle device is not being used, the threads on the muzzle can be covered by a thread protector. The barrel is pinned to the receiver in a modified trunnion, reinforced by ribbing, and is slightly wider than the trunnion used on standard AKM type rifles. Symmetrical bulges on both sides of the front trunnion ensure proper fit inside the receiver.
In Project Reality, the RPK (7.62x39mm) is used by a large variety of irregular forces as their main automatic rifleman weapon.
