The SureFire Optimized Bolt Carrier Group (BCG) for 5.56mm rifles represents a significant advancement in AR-15 platform performance. This innovative BCG features a patented design that enhances reliability, reduces felt recoil, and improves overall weapon cycling. The long-stroke design provides 60% more travel beyond the magazine, practically eliminating bolt-over-base malfunctions. An improved cam path delays bolt unlocking, resulting in a 15% decrease in chamber pressure before unlocking compared to standard BCGs. The included H-weight buffer and custom spring further optimize the system's performance.
