Griffin Armament Enhanced Mil Spec Bolt Carrier Group For 556 / 300BLK Rifles

The Griffin Armament BCG combines an 8620 carrier, 9310 Bolt, 4340 cam pin and extractor. All the proper heat treats, the correct shot peen, and the often neglected post heat treated grind are present. All components are billet machined and all surfaces receive a finish pass in machining for improved surface smoothness. The finish is a deep black finish with remarkable lubricity.

These are assembled to the current military technical data package with permatex'd and properly staked carrier keys. They also feature the current 15,000 round extractor spring design and a Crane o ring for reliable extraction in extreme conditions. In the testing and evaluation phase Griffin ran thousands of rounds in multiple manufacturers rifles without a single malfunction.
