More than just a a new carrier, Surefire has added weights and changed the construction, all with DLC coating and integrated buffer and spring
Many have experimented with the ultimate bolt carrier group. Surefire has come up with something different. Perhaps not revolutionary, but this carrier gives you more than just a pretty fiinsh.
- 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. 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.
