This Noveske small-frame AR-15 bolt carrier group is DLC coated to Noveske specification and machined to USGI specifications from domestically sourced 8620 aircraft-grade steel. It is an M16/M4-profile carrier for AR-15 and M16 small-frame rifles, with a chrome-lined bore and the correct mil-spec gas key already installed.
The gas key is chrome lined, heat treated and properly staked per GI specification, so it is ready to go into a standard small-frame upper. The DLC (Diamond-Like Carbon) finish gives a slick, hard surface that is easier to wipe down after a range session than a bare phosphate carrier.
Specifications:
Fitment: Small-frame AR-15 / M16 uppers only. It is not for AR-10 / .308 large-frame rifles. Lubricate the carrier before first use, have headspace verified whenever you pair a bolt with a new barrel, and do a full function check before live fire.
