A complete bolt carrier group for AR-15 and M16 pattern rifles in 5.56, with a billet-machined extractor and a nitride finish over the assembly. The supplier lists it as new, while our records carry it as used, and the picture on the listing is a stock photo rather than the exact unit; go by the supplier's grade and ask if you want to see the piece itself before it ships.

The carrier group is the part of an AR that does the work, running back and forth in the upper to feed, lock, fire, extract and eject, so a spare is the one component most owners keep on hand. For a South Carolina AR owner this unit is a drop-in replacement for a worn or damaged group, or the starting point for a new upper build; the billet extractor is the part most often upgraded, and here it comes fitted. The nitride treatment covers the full group and wipes clean with little effort after a range session.
