Used in Special Forces units worldwide, the S-552 is a favorite among Anti-Terrorist units. A more compact version of the 550, the S-552 has become one of the most widely used assault rifles in the world. This is a complete clone of TM same model but with a higher power. This is a pretty tight, well made high end gun. Body is rock solid, made of metal and plastic similar to original. Receiver is sturdy plastic. Folding gun stock locks solidly in open. Brass barrel, effective hop-up. This is a great weapon for CQB.
