The AKS-74U has only minor differences from the basic AKS-74 assault rifle.
|AKS-74U short assault rifle|
AKS-74U has a severely shortened barrel, with the gas chamber moved back and appropriately cut down gas piston rod. Since the portion of the barrel after the gas port is very short, a special muzzle device was designed, which is used as a flash hider and the gas expansion chamber (to achieve reliable gas operated action). The front sight base is lowered, and the standard adjustable rear sight is replaced by the flip-up rear (marked for 200 and 400 meters distance), mounted on the receiver cover. The receiver cover is hinged to the receiver at the front and flips up when opened (original AK-74 receiver cover is detachable). Otherwise the AKS-74U is similar to the AKS-74, it has same controls, folding buttstock, and uses same magazines. AKS-74U cannot be fitted with bayonet. Some versions had a standard side-mounted rail for the night or red-dot scopes, and are known as AKS-74UN.
