AR-SOB-A2 (SUPPRESSOR OPTIMIZED BUFFER)
Carefully designed and built from 10 individual components, the longer AR-SOB-A2 suppressor optimized buffer is a spring loaded, staggered impact, urethane buffered design which is compatible with the Armalite AR10 carbine length buffer tube, Griffin AR-10 Maritime Receiver Extension, or "Vltor A5" length tube and utilizes the A2 rifle length spring. Engineers of some note going back to people who worked with Eugene Stoner have held an opinion that the A2 rifle length action spring with its greater number of coils promotes smoother operation and better reliability than the carbine spring. The AR-SOB-A2 in conjunction with the Armalite AR10 Griffin AR-10 Maritime Receiver Extension or "VLTOR A5" length tube allows the 5.56mm or 300BLK AR15 to be compatible with the A2 action spring. The reciprocal and non-reciprocal weights are nearly identical to the AR-SOB buffer. In conjunction with shock dampening brass weights, the AR-SOB-A2 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 more controlled motion tolerances, allowing precisely controlled timing and forced sequential impact of buffer weights interacting with the rifles operating system. The AR-SOB-A2 weighs 5.6 ounces, and can be used in suppressed 5.56mm rifles as a replacement for the M4 carbine series buffers, when used in conjunction with the AR10 mil-spec CAR receiver extension, Griffin AR-10 Maritime Receiver Extension, or "Vltor A5" buffer tube, AND AR-10 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 failures and mechanical failures of critical system components.
Suppressors further increase system operating speed and exacerbate the over-gassed condition. An AR-SOB-A2 will work to resolve these issues by allowing a carbine to run very similarly to the original product improved, M-16A1 "Sturtevant" rifle length buffer, with the original designed A2 rifle length spring, and longer AR-10 Car or "Vltor A5" tube.
Brass weights and heat treated 17-4 Stainless Steel construction
Staggered impact hybrid buffer design
Rifle buffer function in a CAR system size for unsurpassed reliability
Requires AR-15 in 5.56mm or 300BLK and AR-10 car, Griffin AR10 MRE, or "Vltor A5" Car buffer tube. Also Requires A2 action spring. *Warning do not use this with a standard AR15 extension/car spring"
