    Colt BCG

    No markings what so ever, no Colt package, so there is no way to know what you just received. Colt could do a lot better, and it should be stated in the description of what to expect

    I needed this BCG for a clone build. The price was right and the shipping was spot on!

    Good bolt

    Over all the bolt is great but the marking were ok. I was hoping that the marking would be more visible, the MPC was stamped on the bolt ok and the C was very very faint, looked to be hand etched. I would have liked deep letter stamps to clearly identify it is a Colt bcg. It did have the Crome lining and deep punch marks on the two Allen head screws.

    Colt BCG

    Absolutely no proof that it’s a colt. The only “stamp” I can find says “MP” on the bolt, no “C” located anywhere on the bolt or bolt carrier. I’m a little skeptical if it’s the real deal or not as every picture I see online say “MPC” on the bolt and/ or has a “C” on the bolt carrier. Would love some info on who to reach out to to verify

    True and complete Colt assembly!!! The markings are really faint especially the "MPC" on the bolt, but they are there. This is the way Colt is marking them nowadays. Correct new copper colored extractor spring, etc. No complaints at all, fast shipping and good price compared to all other gougers!!!

    Genuine Colt / MPC markings

    Posted by Thomas Q on 8th May 2021

    I received 3 Colt Bolt Carrier Groups, one carrier was "C" stamped and the other 2 had the newer "C" laser engraved. All three bolts where "MPC" marked. Exactly what I wanted!
