R u guys effin retarded. No offense intended to actual retards, but think about it you've went back and changed you attachments, yet you've never had a silenced M4 with RDS, have you? Sorry to inform of you this but you can first select the grip then change to RDs then tell yourself that you've done it, if it'll make you feel any better.
Moved to Call of Duty 4 Glitches. Next time, just report it, we don't need three posts saying "wrong section" it's plus post counting and considered spam.
