ADM's bolt carrier was critically accessed at the component level. Every component was processed in accordance with the latest TDP including assembly, staking, all heat treats and shot peening to specification. Every component is given a finish pass for optimal surface finish, and grinding is actually done post heat treat where most manufacturers use shortcuts such as CNC machining post-heat treat, or no post heat treat machining at all. Half a dozen Melonite QPQ processing facilities were evaluated before selecting the finest corrosion resistant lubricous finish available. The BCG is so glassy smooth it requires no break in period. Consulting with a group of armed professionals with over 30 combined years of field use of M16 family rifles, the TE testers unanimously agreed that the ADM BCG was the finest they had seen. To quote one of the testers- "I'm impressed- I've been issued 16 Colt rifles and the ADM Bolt Carrier Group BCG is a world apart. That achievement is phenomenally impressive to me." The ADM bolt carrier is the finest Bolt Carrier Group BCG available today.![]()
