15% extra power

by Hotdogjr, Verified Owner from MD, United States Written on July 19, 2026

Used the A2 version in BCM Mk2 system with a T2 buffer for a SOLGW 13.7 midlength gas upper. Maybe don't need it but figured why not? Very smooth and soft recoil impulse. Cycled but NO lock back with Wolf steelcase. Worked without malfunction with PMC bronze .223 and all my m193 spec ammo from Winchester, IMI, PPU, GGG and even Wolf Gold.

Extra Power Spring

by arak1547, Verified Owner from OK, United States Written on May 22, 2026

This is an awesome product that I purchased because Optics Planet did not carry the Sprinco line. I put it in my AR .45 and found it too powerful with the 9 oz. buffer and began seeing bolt-bounce and doubling. Will try getting a 6 or 6.5 oz. pistol buffer and retry the set-up. It is definitely worth the money and is probably as good as a Sprinco.

Pros:

Easy to install

Cons:

None

Best Used for:

AR 10 or direct blow-back pistol tune with a 6 or 6.5 oz. buffer.

Soft shooting

by Big Jon, Verified Owner from TN, United States Written on April 8, 2026

It helps with ejection and keeps the gun from beating itself to death when over gassed.

Pros:

Softer shooting experience

Cons:

Won't completely fix the problems from an over gassed gun.

Best Used for:

Suppressed shooting or over gassed gun, like a 10.5 11.5 ect.

great for tuning

Works great for tuning with atrius selektor, this with a H2 or h3 buffer let's you fine tune you cycling rate.

Extra power spring

by Steve, Verified Owner from KY, United States Written on January 20, 2026

I don't have a sprinco blue to compare to but I would say its Griffin's equivalent. Quality is great. Took my over gased aero 16" midlength from a 1:30 ejection pattern to a 3:00-3:30 when I paired it with the sob buffer. So far so good, can't speak for longevity but Griffin makes good stuff

If you’re looking to tune your over gassed rifle this is the buffer tube you need.
