VKTR Piston BCG Combat Match Bolt Carrier Group for AR-15

VKTR precision machined one-piece piston bolt carrier for AR-pattern piston-driven receivers with a patented long advance cam path that unlocks the bolt at 22.5 degrees for an additional 2 degrees of dwell time to reduce residual chamber pressures and help avoid cam pin contact with the receiver wall. Paired with the VKTR Combat Match Bolt featuring a fully-supported bolt face with wider lugs and a shot-peened surface treatment. Includes a precision cam pin with enhanced dimensions/tighter tolerances for improved shot-to-shot consistency. Carrier is finished in thin dense chrome for ease of cleaning and long-term wear resistance. Package contents: VKTR Combat Match Bolt Carrier Group with combat match bolt.
