Can't Ask for Anything More!!!
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
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!

Colt BCG
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.
