Carefully designed and built from 9 individual components, the AR suppressor optimized buffer is a staggered impact, dual urethane buffered design. Utilizing non reciprocal weight and reciprocal weight similar to the A2 rifle length buffer, in conjunction with shock dampening brass weights, the AR-SOB offers increased system dwell time, reduced bolt speed, and enhanced chambering reliability. Through integration of a shorter platter of CNC machined weights and a telescoping buffer head, the AR-SOB has 30-50% tighter tolerances, allowing precisely controlled timing and forced sequential impact of buffer weights interacting with the rifles operating system. The AR-SOB weighs 4.9 ounces, and can be used in suppressed 5.56mm rifles as a replacement for the M4 carbine series buffers, and also in 308 carbines as a replacement for H2 and H3 buffers when used in conjunction with the AR10 mil-spec CAR receiver extension and AR10 CAR action spring.

The buffer is one of the more overlooked components in most rifles. In the current market, cost constraints and a desire for rifles to run with cheap, underpowered, steel jacketed ammunition are driving forces for many firearms companies who are involved in what appears to be a constant race for the bottom. Most rifles are aggressively overgassed, and supplied with cheap, light CAR buffers which are employed to reduce system cost, robbing rifles of necessary weight for reliable chambering with fouled chambers, and encouraging premature unlocking of the bolt, causing undue extraction stress, contributing to operational and mechanical failures of critical system components.

Suppressors further increase system operating speed and exacerbate the over-gassed condition. An AR-SOB will work to resolve these issues by allowing a carbine to run similarly to the originally product improved, M-16A1 "Sturtevant" rifle length buffer, despite the reduced internal length of the CAR receiver extension.

    Good Buffer

    This is the best made buffer I have purchased yet. Great fit and finish, well machined. Tamed my AR nicely.

    Excellent buffer for suppressed guns. Makes a huge difference. Combine it with the snach charge handle and you are all set.
