I have one new Colt M16A1 Complete upper. Barrel 20" with A1 flashider Barrel marked "C MP B" with trangle handguards. Still has cardboard tube in barrel. Upper receiver (small hole) marked "C H" A1 sights. I have added a Colt charging handle and Colt M16 "C" marked carrier with Colt "MPC" marked bolt. Bolt and carrier have been used but are in excellent condition.
Upper receiver has forward assist and no case deflector.
Pics on request, I'm not sure how post them
