Zastava M72 Caliber: 7.62 x39mm Rare and completely original Zastava M72. The rifle is fully authentic and includes bipod (see images). The rifle is used but is in good condition. Description of this model: The Zastava M72 chambers and fires the 7.62×39mm M43 round. It is a gas-operated, air-cooled, drum-fed firearm with a fixed stock. This weapon is a near copy of the Soviet RPK light machine gun. There are a few differences on the M72/M72A. It does not have a scope side rail mount, the butt is also different, having the shape of a regular AK-47 rifle. It has a reinforced receiver, night sights and no carrying handle. The barrel also differs from other RPK rifles because of the cooling fins to help with heat dissipation from prolonged fire. The M72 only appears with a heavy profile barrel as opposed to Russian and Romanian RPK rifles that can come in both light or heavy barrel configurations. -- Free shipping.
