AKM, this means they cannot use an AKM compensator or blank-firing device. Commercial versions of the Type 56 may or may not have a threaded muzzle. The front sights are fully enclosed with a hood, compared to the AKM and AK-47 which have partially opened "ears". The front sight base has a shape similar to the AK-47 and may also have a SKS style folding spike bayonet (nicknamed the "pig sticker") as opposed to the lug for detachable knife bayonets on the AK-47 and AKM. There are three different types of spike bayonets made for the Type-56 and the Type-56 assault rifle is the only AK variant that utilizes a spike bayonet. Certain versions of the Type 56-II support standard AK-47 and AKM bayonets. Has the double hook disconnector of the AK-47 rather than the single hook disconnector of the AKM. As a result it also lacks the hammer release delay device of the AKM, otherwise known as the rate reducer. The lack of hammer retarder is perhaps due to a preference of a slightly higher rate of fire, and simplicity. And did not have anything to do with thickness of the receiver, as the RPK included the hammer retarder also. Has "in the white" bolt carrier, while the AKM bolt carrier is blued. Also lacks the various lightening cuts, though has a flat firing pin. Many civilian/export versions have a firing pin spring to prevent possible slamfires when used with softer commercial primers as opposed to the original free floating type. Some were added by importers rather than being a factory equipped part. Has the flat/smooth handguards of the AK-47, with a storage slit underneath on versions equipped with the spike bayonet. Uniquely, it lacks vent cuts on the upper gas tube heatguard. Also retains a metal ferrule that sits between the lower handguard and the front of the receiver that the AK-47 had. The pistol grip is the same kind as the AK-47 being made out of wood with a metal ferrule between it and the receiver instead of the later one piece bakelite like the AKM. The Type 56-II uses the AKM style with slightly different shape. The trigger guard is held in place with only three rivets (one on each side and one beneath the pistol grip) where as the AK-47 and AKM have five (two on each side and one beneath the pistol grip).
