Felt recoil was enormously reduced using this compared to a standard milspec buffer and spring, I was actually very shocked at how much more stable and flat my rifle felt to fire. Was like getting lightly struck on the shoulder by a 4 year-old, this buffer will just make your gun shoot like a dream you will not be disappointed

These buffers work excellently. I have 3 of them. They soften the recoil and seem to help keep my PCC fat and on target. I am using them with the spring removed. Great product and incredible customer service. Thank you!

I just got the Duty buffer and it exceeded my expectations fully! My rifle has absolutely “ZERO” muzzle rise/flip, and the ‘zing’ you hear on regular buffer springs is gone too. So much smoother to use and follow up shots are NOT a problem as you never leave you intended impact point. Worth every cent spent.

I bought the duty buffer after using their competition buffer in my match gun. So far I have no complaints concerning reliability and the gun shoots faster/ flatter than it did before.

I wish I would have bought a few more (ultimate sad face) 😔. I originally bought one as a test for my 12.5 and goodness, I noticed it was very mellow when firing as opposed to the aggressive action of the buffer spring. Needless to say when they are back in stock, I gonna snag a few for current and future rigs!

bought this buffer tube and honestly i was blown away paring it with the muzzle break the recoil was changed completely i was able to get back on target so much faster than with a stock buffer hands down it was 100% worth the money and install wasnt bad at all
