a dealer here in az ,AZEX, just got 2 of the SOW suppressors in the mail....no customer name with it (and he had a couple customers who ordered them) no instructions. he said hey are unfinished. the caliber adaptors just rattle around inside and he doesn't know if there's suppose to be more parts with it. there were some loose orings in the box. basically said it looks like a complete piece of crap and recommends it not be used lol.
