The AK-74 is a well-known assault rifle that was designed in 1974 by Mikhail Kalashnikov. It has been used by several countries worldwide since the 1970s, although it is primarily associated with the Soviet Union. The rifle uses a 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge used in Kalashnikov’s earlier automatic weapons for the Soviet armed forces.
The AK-74 saw its first service with Soviet forces during the Afghanistan conflict in 1979. According to the head of the Afghan bureau of the Inter-Services Intelligence, the intelligence agency of Pakistan, the CIA paid $5,000 for the first AK-74 captured by the Afghan mujahideen during the Afghan-Soviet War.
The AK-74 is an adaptation of the AKM assault rifle, designed by А. D. Kryakushin’s group under the supervision of Mikhail Kalashnikov. The AK-74 features several design improvements that were made to convert the rifle to the intermediate-calibre high velocity 5.45×39mm cartridge. Early models of the AK-74 are reported to have been converted AKMs, re-barreled to 5.45×39mm. Roughly 50% of the parts in the AK-74 and AKM are the same, including pins, springs, and screws.
Compared to the AKM, the AK-74 has a better effective firing range, accuracy, and reliability, which were main development goals. The rifle’s operation during firing and reloading is identical to that of the AKM. After ignition of the cartridge primer and propellant, rapidly expanding propellant gases are diverted into the gas cylinder above the barrel through a vent near the muzzle. The build-up of gases inside the gas cylinder drives the long-stroke piston and bolt carrier rearward. A cam guide machined into the underside of the bolt carrier along with an ejector spur on the bolt carrier rail guide rotates the bolt approximately 35° and unlocks it from the barrel extension via a camming pin on the bolt.
The moving assembly has about 5.5 mm (0.2 in) of free travel which creates a delay between the initial recoil impulse of the piston and the bolt unlocking sequence. This allows gas pressures to drop to a safe level before the seal between the chamber and the bolt is broken. Since the Kalashnikov operating system offers no primary extraction upon bolt rotation, the 5.45×39mm AK-74 bolt has a larger extractor claw than the 7.62×39mm AKM for increased extraction reliability. Other minor modifications were made to the bolt and carrier assembly.
An AK74 80% receiver would refer to a partially completed receiver that is not yet classified as a firearm and would require additional machining to become a functional receiver for an AK74.
