Products / .308 Piston - Anti-Tilt


Anti-Tilt Piston Buffers

This is the original Anti-Tilt buffer, designed to prevent excessive wear to the receiver extension (buffer tube) caused by bolt carrier tilt/cant in the popular piston-driven ARs. The elongated head of the buffer is centered in the bolt carrier by the 'nipple'. This setup prevents contact between the bolt carrier and the buffer tube.

Tested and proven with Adams Arms, POF, Stag Arms, Ruger, CMMG, LWRC, LMT, HK, PWS, Osprey Defense, Sig, and others.

Please notify me via email after placing your order if you have an LMT or ARES Defense upper, their carriers are slightly different and require a custom buffer (same price). Newer PWS .223 systems also require this special buffer.

The buffer is constructed from 303 Stainless Steel for a lifetime of trouble-free performance. There are no moving parts to break, and no messy fluids/powders to leak out. A foolproof design for flawless operation of your weapon.

The head is polished to further reduce the possibility of buffer tube damage.

The .308 Carbine buffer includes a special custom buffer spring that is required for proper function.


.308 Rifle A/T Buffer - 11.5 oz. - $125

.308 Carbine A/T Buffer + Special Spring - 6.5 oz. - $140




Sig-Sauer 716 .308 owners - I do not recommend A/T buffers for these guns.
