XH Carbine Buffer - 8.5 ounces - $125

XH Carbine Buffer + Wolff XP Spring

XH Carbine Buffer Only

This Xtra-Heavy buffer is the heaviest standard carbine length buffer on the market. At 8.5 oz it weighs nearly three times as much as OEM AR15 carbine buffers.

Machined from solid 303 Stainless Steel with Tungsten anti-bounce internal weights. Includes a Stainless Steel roll pin for a lifetime of trouble-free performance. The head is polished for an extra smooth finish that won't cause damage to your buffer tube.

The original intent was to reduce rate of fire in full-auto M16s. The XH buffer weighs nearly three times as much as a standard AR15 carbine buffer so it dramatically decreases the rate of fire, while maintaining reliability. My customers with suppressed weapons love this buffer.

Helps reduce felt recoil for the the 'Big-Bore' calibers. Very effective with 6.5 Grendel, 6.8 SPC, .450 Bushmaster, .458 SOCOM, and .50 Beowulf. Can also be used with 9mm, .45 ACP, .40 S&W or 10mm.

I recommend Wolff XP buffer springs for maximum reliability.

I strongly recommend this buffer if any of the following conditions apply:

  • If you will be shooting with a suppressor. (Your gun will still run fine unsuppressed with standard ammunition.)
  • If you will be shooting hot hand loads or very heavy bullets.
  • If you want maximum recoil reduction.

For .308 Rifles:

If you have an extended (7-5/8" deep) receiver extension on your gun I recommend an XH carbine buffer and a .308 rifle buffer spring. This includes VLTOR A5 tubes and the Magpul UBR Gen2 stock. Many .308 rifles come from the factory in this configuration - LaRue, LMT, LWRC, POF, S&W, etc.

If you have any doubt either measure your current buffer or check the inside depth of your buffer tube. If your buffer is 3-1/4" long and your tube is 7-5/8" deep this is the best buffer spring combo for your gun.

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.
