All critical parts are coated with EXO Nickel Boron technology that provides permanents dry lubricity, extreme durability, increase wear and corrosion resistance. Just a quick video to show you the difference between a ar15 bolt carrier group and a full auto bolt carrier group. The firing pin is not shrouded on a semi-BCG and they weigh a bit less. Had exactly what I needed, super fast shipping. This Bolt Carrier Group (BCG) comes fully assembled and ready to drop into most mil spec AR15 upper receivers. This is a Mil Spec Colt Bolt Carrier Group Assembly with all the markings. New Colt, C Marked Carrier, MPC Marked Bolt Bolt face edges are beveled and MPC marking is very faint. Bolt carrier has a faint “C” marking and color is more of black than greenish hue that Colt uses in the past. This allows for increased pressure in the chamber and therefore higher velocity rounds as the bolt is closed longer and allows more powder to be burned safely. When the bolt goes forward it rotates, locking the breech and sealing the chamber. So buyer beware, all these "new" BCGs have parts of their finish worn off already showing bare metal. The issue with closed-bolt firearms such as the AR-15 is that there’s a locking mechanism on the bolt. The new AR-V is similarly named after Palmetto State Armory’s A K -V Kalashnikov 9mm pistol, which also shares the same magazine pattern and 9mm caliber.

But it sounds like you already own a complete rifle with a semi-auto that functions fine. Palmetto State Armory has a large selection of bolt carrier groups for your AR-15 rifle or pistol.

I received 3 Colt Bolt Carrier Groups, one carrier was "C" stamped and the other 2 had the newer "C" laser engraved. The weight of a Bolt Carrier Group, or BCG, in an AR15 platform has been modified from the original weight of a full-auto BCG in an attempt to prohibit full-auto conversion of otherwise non-NFA weapons intended for commercial civilian use or sale. I think if youre building a gun from scratch you might as well go with the full-auto option. Palmetto State Armory recently released a 9mm AR-15 pistol that accepts the popular CZ Scorpion EVO 3 magazines. No complaints at all, fast shipping and good price compared to all other gougers!!! Correct new copper colored extractor spring, etc. This is the way Colt is marking them nowadays. True and complete Colt assembly!!! The markings are really faint especially the "MPC" on the bolt, but they are there.
