Just like the add says I traded off the RR upper to this wilson 1/9 twist BBL w target crown and attached it to a BM A2 upper. This would be a great NM upper. Wilson barrel has way less than 500rnds (maybe more like 300ish). Very low rnd cnt A2 upper is very nice as well (looks to be only test fired). Only flaw I could see was someone installed a scopemount ontop of the carry handle. I actually took my thumb and rubbed out one so you might be able remove them with a rag and some clp. So there are some very minor slight blemishes (NO CH or BCG, sorry).
