Legit Colt BCG
This BCG is identical to the BCG that came in my Colt AR15A4 purchased earlier this year. Carrier is marked “C” and the bolt itself is very lightly etched with “MPC”. The carrier has the nice slick phosphate finish unlike some other second-tier manufacturers.

Colt BCG
Carrier is marked with a “C” and bolts are marked “MPC”. Chrome lined carrier. Looks exactly like the BCGs in my Factory Colt Rifles, except the MPC is easier to see. It’s good to go.
