    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!

    Overall it looks “milspec”. Bolt carrier has a faint “C” marking and color is more of black than greenish hue that Colt uses in the past. Bolt face edges are beveled and MPC marking is very faint.
