The Highest Performing Buffer on the Market – Eliminates Bolt Bounce, Controls Muzzle Rise, Cuts Down Felt Recoil and Overall Noise

The Buffer that offers the best performance at a reasonable price is finally here on AT3. Introducing Spike’s Tactical Tungsten Buffers, which use high-density material to provide an advantage over the competition. These buffers help in eliminating bolt bounce, noise, cut down felt recoil, as well as controlling muzzle rise in full auto mode.

The T1 and T2 buffers reduce noise with their internal weight, which is actually a crushed tungsten powder.  Added and even distribution of mass helps eliminate bolt bounce.  The T3 buffer uses more traditional sliding tungsten weights, and comes in at 5.5 pounds, making it a good option for pistol-caliber builds.

So far, so good

Definitely deadens the action impacts, more of a thump than a slap type of feel. Softens one part of the big bore recoil in an AR, probably easier on impact stresses in the action too. I'll see how it works over time...

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Very nice

Works fantastic in my 16 in mid length rivle with carbine style buffer. Using it with a sprinco blue enhanced buffer spring.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

Amazing buffer

I buy these for every AR I have. Amazing buffer, quiet sound and extremely smooth, not clunky as with traditional weights. If you are looking for a cheap but substantial upgrade, this is highly recommended. The T2 is fairly universal for most.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
