Excellent condition, less then 500 rounds, 20" BM HBAR chrome lined barrel, DCM free float tube with A2 handguards, .052" front blade and 1/4 MOA rear sights with .040 rear sight insert, all built by Bushmaster. Incl. Bolt, carrier and charging handle. No marks/scuffs on reciever (except for the usual brass dings on the deflector), VERY minor rub mark on bottom barrel under front sight base. Really excellent condition. Went to their "real" DCM upper, and have my M4 for fun, so no longer need. $300 OBO CONUS.
