Carefully designed and built from 10 individual components, the AR suppressor optimized buffer is a spring loaded, staggered impact, urethane buffered design. The reciprocal and non-reciprocal weights are 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 more controlled motion 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 failures 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 original product improved, M-16A1 "Sturtevant" rifle length buffer, despite the reduced internal length of the CAR receiver extension.

    Yo for real everyone should be buying two of these. One to make your gun run flawlessly, and you can use the other one as a substitute for that fake gold rosary that was Los Angeles sourced.

    Excellent quality. Works perfect and feeds supers and subs in my .309 BLK without hesitation. Works equally well for my .223/5.56 upper.

    Excellent buffer, handles recoil well on 556 and 300 Black, and does pretty well running 300 subs too. I have one of these in all my rifles, definitely worth the investment.

    Great buffer!

    I bought this to use with a foxtrot mikes pistol 9mm ar build with a supressor and folding stock adapter that had a lot of recoil. I Installed this replacing the Spikes heavy buffer I was using and it lessened felt recoil by about 1/2 and the gun runs great. Very pleased, I may buy another one to try on my supressed 5.56 well.

    Badass product, the quality is present in every single item i have from Griffin. This buffer was no exception . Amazing craftsmanship, pure reliability, and amazing service. I recommend any of their products to everyone who wants quality over quantity in the firearms industry. -J

    One of the few AR products I really find useful when running a suppressed rifle ... quality top notch. You have to make sure your buffer tube is drilled proper for gas bleed out (or use Griffs maritime).
