I have for sale a like new (possibly unfired) and recent production Colt M4 upper assembly. The receiver is marked M4 above the gas tube hole and C behind the brass deflector. It also has T-markings and M4 feedramps. The FSB is F-marked. The barrel is M4 gov't profile and marked C MP 5.56 NATO 1/7. Upper includes charging handle, A2 flash suppressor, M4 handguards, and side sling adaptor. Bolt, carrier, and carry handle are not included. This is really a beautiful piece and I am only selling to finance glass for a bolt gun.
