Note: The buffers on this page are designed to fit bolt carriers with a 5/8" nominal inside diameter. This includes the majority of all piston systems. Some ARES Defense, LMT, PWS, and a few other carriers have a 1/2" nominal inside diameter. Anti-Tilt Buffers for those systems are available here: 1/2" Anti-Tilt Buffers
PLEASE VERIFY BEFORE ORDERING.
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 completely 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.
These buffers are constructed from 303 Stainless Steel for a lifetime of trouble-free performance. None of our Heavy Buffers have messy powders or fluids inside that will eventually leak (they always do) and muck up your gun's internals.
The reciprocating weights inside the carbine buffer provide a "Dead-Blow" effect that helps prevent bolt-bounce.
We recommend using EA1095 AR-10 rifle buffer springs with the rifle buffers. OEM springs from other manufacturers and lesser aftermarket springs (including Sprinco ROYGBIV) may cause malfunctions.
The .308 Carbine buffer includes a special custom buffer spring that is required for proper function. Flat-Wire springs are not recommended for any application.
.308 Rifle Anti-Tilt Buffer - 11.5 oz.
.308 Carbine Anti-Tilt Buffer - 6.5 oz.

Takedown procedure with an Anti-Tilt buffer installed is as follows:
- Push out both pins.
- Slide the upper receiver forward slightly.
- Lift it away from the lower receiver.
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.
Specifications are subject to change without notice.
