I just checked my one Colt AR-15A2 and it's a Pre-Ban. How can I tell if a Colt Sporter is Pre-Ban? By the serial number. AR 15, AR-15, however you want to spell it We are very fortunate to live in WA state that allows a face to face private party transaction to be done without any paperwork required. I'll throw in a third mag as well as one of them needs the feed lips adjusted a little. Serial is a CCH 002XXX.Ī few handling marks, but the bore and receiver are pristine. Incredibly nice Colt AR15 A3 style rifle with removable carry handle and flat top.
