Colt 6920 upper. A few marks here and there. Let me know if you need to see any areas more closely. Maybe 500 rounds total through it but was carried a decent amount. Includes MBUS rear sight. Upper has C, keyhole and M4 markings. Barrel had C MP markings and 05/11 date code under the handguard. BCG has C, bolt has MPC. Not looking for trades. $475 shipped.
