AKRIVA Type 56-1 Gas Blow Back Airsoft rifles are 90% steel construction both externally and internally, with the receiver and dust cover made using the same type of stamped steel and surface treatment finishings that Norinco factories use to produce real-steel Type 56s and an under folding butt stock that uses a solid double locking arm mechanism. They feature a forged steel front and rear trunnion that are reinforced with proper steel rivets, all steel trigger assembly including hammer, sear, trigger and trigger bar. The hammer spring is also a 1:1 replica of the real-steel wire spring, making the whole assembly extremely authentic. The bolt carrier is also forged steel and comes with a dummy long stroke piston assembly, where the piston head is visible in the gas port. The rear sight block is also reinforced and made of steel and features an elevation-only adjustable rear sight plate. Type 56-1 is also fitted with authentic Type 56 wooden foregrips and pistol grip, while its under folding stamped steel stock is solidly attached to the rear trunnion. The AKRIVA rifles come with a 7.62x39mm-style curved stamped steel magazine with a true maximum capacity of 30 rounds of 6mm BBs which is powered by green gas
