can I use this buffer in a 20" Ruger .308 SFAR? Manufacturer Answer

Helpful Positive Review griffin armament suppressor optimized buffer black arsob by Dredd, May 9, 2020
if you run your ar suppressed this is a must! I love this little s.o.b. . But no in all seriousness this will help a ton with recoil! This will help you stay on target better. It will also help you stay on target longer.

Helpful Positive Review Solid buffer for your suppressed rifle by JMS, June 1, 2020
looks cool, has great fit and finish. I haven't been able to test it yet, but running the action feels very smooth. I think it is going to work great. Feels about the weight of an h2 buffer. Fit into my spring fine. Price isn't much more than a quali...

Helpful Positive Review Griffin suppressor buffer by Kool, Verified Owner, May 17, 2024
Solid. Got it to help with the gas issue I was having with my suppressor attached. Helped out for sure. Still going to put an adjustable gas block on as well.

Helpful Positive Review SOB Saved My SBR by SweetM16, June 15, 2020
I love my Griffin Armament M4SD suppressor. But when I ran it on my 10.5 SBR, the rifle would jam. Once I started running the Griffin Armament Suppressor Optimized Buffer, my SBR functioned like a dream!

Helpful Positive Review Excellent subsonic buffer by Rob, July 29, 2020
I got this buffer to fix some issues I was having with cycling ammunition in my 300 blackout pistol. After changing this buffer not only was my recoil more manageable but the rifle functioned reliably.

Product Info for Griffin Armament Suppressor Optimized Buffer

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.image

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.
