Y/M standard AR Bolt Carrier Group As with all of our carriers we leave material on all critical areas then send them out for heat treat. Next we precision grind the carrier inside and out to remove any distortion caused by the heat treat process. All of our standard carriers have 30% wider rails than the typical Mil Spec carrier to give you more contact area in the upper receiver.Weight: 11.3 ounces. Available in AR15 or M16 type.
