This video introduces the SureFire Optimized Bolt Carrier (OBC) for the AR-15 platform. Paul Levy from Brownells' new product acquisition team discusses the design by Jim Sullivan, an original M16 designer, highlighting subtle but impactful modifications to the carrier, recoil buffer, and spring. These changes aim to increase carrier travel, leading to a gentler recoil impulse, less violent cycling, and improved reliability in stripping the next round from the magazine. The video concludes with a visual comparison of the SureFire OBC against a standard bolt carrier group within a rifle.
