AR-15 Bolt Carrier Group

The bolt carrier group is an extremely critical component in keeping your rifle running smoothly. This is the same bolt carrier used in our Mark 1 and Mark 2 series rifles.

Our carrier is manufactured from 8620 steel, while our shot-peened bolt is made from either 9310 or carpenter 158. The bolts are batch high pressure tested and individually magnetic particle inspected after heat-treat to ensure no microcracks.

the steel choice, combined with the Black Nitride treatment, results in a hard-use, abrasion & corrosion resistant bolt carrier group with excellent lubricity.
