With that, you might be thinking about tuning your AR. 300 Blackout round is perhaps the best option for urban tactical scenarios as it gives you the performances of a 7.62x39mm round with the standard size AR magazines. An AR-SOB will work to resolve these issues by allowing a carbine to run similarly to the original product improved, M-16A1 "Sturtevant" rifle length buffer, despite the reduced internal length of the CAR receiver extension.There is no doubt that the. Suppressors further increase system operating speed and exacerbate the over-gassed condition. 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 failures and mechanical failures of critical system components. 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.
The buffer is one of the more overlooked components in most rifles. 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. Through integration of a shorter platter of CNC machined weights and a telescoping buffer head, the AR-SOB has more controlled motion tolerances, allowing precisely controlled timing and forced sequential impact of buffer weights interacting with the rifles operating system. In conjunction with shock dampening brass weights, the AR-SOB offers increased system dwell time, reduced bolt speed, and enhanced chambering reliability. The reciprocal and non-reciprocal weights are similar to the A2 rifle length buffer.
Carefully designed and built from 10 individual components, the AR suppressor optimized buffer is a spring loaded, staggered impact, urethane buffered design.
