SMG - 5.45x39mm Soviet - Russia/CIS - 700 RPM - The AKSU-74 is radical modification of the basic AK74 rifle.  It reduces the full size assault rifle into a SMG-sized package.  It retains the penetration of its rifle cartridge at the cost of extreme flash and blast signatures.  In the CIS, it is a favorite with police, special forces, airborne troops and armored units. D.E.
