Bolt Carrier Groups
Shop AR bolt carrier groups for builds, repairs, and performance-focused upgrades. The BCG is one of the hardest-working parts in the rifle, handling cycling, feeding, extraction, and overall reliability. Choose based on caliber, coating, gas system, and the type of build you are putting together.
⚠ ▼ AR Bolt Carrier Group Fitment Warning
Bolt carrier groups must match your caliber, barrel extension, gas system, and receiver pattern. AR-15, AR-10, .300 Blackout, 9mm, and specialty builds may require different BCGs.
