Products / AR-15 Piston - Anti-Tilt
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, and others. Please notify me if you have an LMT, their carriers are different and require special dimensions (same price). All other makes use the same 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 hand-polished to further reduce the possibility of buffer tube damage. Internal weights are either steel or Tungsten, depending on desired finished weight. Total mass can vary from 4.5 ounces up to 8.5 ounces.
This product is for carbine-length stocks only, a spacer ($10) is required for use with rifle-length stocks. I also offer rifle-length Anti-Tilt buffers, see below.
The H3 (5.5 ounce) buffer is recommended for most applications. If you are running a suppressor it is a good idea to consider upgrading the the XH (8 ounce) buffer.
Please Note: I strongly recommend using Wolff XP carbine buffer springs with these buffers. Some standard OEM and aftermarket springs from other manufacturers will cause malfunctions. 'Flat-Wire' springs are not recommended in any case.
This kit allows 'tuning' the buffer to a your specific firearm/ammo. Total weight can be adjusted from 4.25 to 6.25 ounces, or up to 8.5 ounces with the optional Tungsten inserts, sold below.
Only available with purchase of an A/T Buffer kit.
This Delrin spacer allows you to use any carbine buffer in a rifle-length buffer tube. Now you don't have to buy a new buffer If you change your stock type.
Also available for AR-15 rifles and for .308 piston guns in rifle and carbine sizes.
The .308 Carbine buffer includes a specially modified spring that is required for proper function.
