Description:
SF-OBC-556 Optimized Bolt Carrier Group Optimized Bolt Carrier Group for M4 M16 AR-Variant Rifles amp Carbines 399.00 You save Current Stock QTY Contact Dealer SureFire s next-generation bolt carrier group, optimized for 5.56 mm .223 caliber rifles and carbines Long-stroke design increases reliability when firing suppressed or unsuppressed Includes optimized bolt carrier, buffer spring and long-stroke, H-weight buffer Double Down on Reliability. nbsp Invented by Jim Sullivan, one of the original designers of the M16, the SureFire Optimized Bolt Carrier OBC doubles the reliability of any M4 M16 AR variant weapon system during suppressed and suppressed firing. Its patented design allows more time for reliable feeding of ammunition from the magazine and nearly eliminating bolt-over-base malfunctions. The OBC also delays unlocking of the bolt during the firing sequence, which allows expanding gases more time to exit the bore, in turn reducing back-pressure gases exiting the upper receiver group. Additionally, the neutrally balanced counterweight improves carrier and barrel extension lock-up, nearly eliminating bolt bounce. The OBC reduces felt recoil for better target tracking and greater weapon control when firing. Coated with an advanced anti-friction coating, the OBC resists friction during use and makes cleaning easy. nbsp Read More 0 5 0 Reviews Write a Review
