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, Ares Defense, CMMG, HK, LMT, LWRC, Osprey Defense, POF, PWS, Rock River, Ruger, Sig, Stag Arms, and many others.

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 Rifle Buffer Spring - $15

.308 Carbine A/T Buffer + Custom Spring - 6.5 oz. - $150

Note: We cannot guarantee proper function with subsonic ammo. There are significant differences in specifications among the various brands of ammo and firearms manufacturers. Some guns will run great with almost any ammo, other guns may not function reliably with any subsonics. This is all beyond our control.

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