CAR-10 XH Buffer - 6.5 ounces - $125

CAR-10 XH Buffer + .308 Carbine Buffer Spring



CAR-10 XH Buffer Only



.308 CARBINE Buffer Spring - Custom


Extra-Heavy model for suppressed weapons, or for maximum recoil reduction in non-suppressed guns.

Includes a Stainless Steel roll pin for a lifetime of trouble-free performance. The head is hand polished for an extra smooth finish that won't cause damage to your buffer tube.

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 handloads or very heavy bullets.
  • If you want maximum recoil reduction.

A CAR-10 XH buffer will allow you to use any AR15 collapsing stock (Magpul/LMT/VLTOR/Ace/etc) on your AR10, SR25, LMT, LWRC, POF or DPMS-pattern .308 rifle. This is strictly a 'Drop-In' part, no gunsmithing or modifications are required.

CAR-10 XH buffers are shorter and heavier than standard carbine buffers. Constructed of 303 Stainless Steel with a sliding Tungsten anti-bounce counterweight. Heavy buffers reduce felt recoil for the shooter, and minimize wear and tear on the gun. Many users report that the CAR-10 XH buffer corrected reliability issues with their firearms.

This product is specifically recommended by Magpul for use with their carbine stocks on .308 ARs. (Call them!) CAR-10 XH buffers also work great with any other stock using a standard 7" carbine buffer tube.

I recommend using .308 Carbine Buffer Springs with these buffers. These springs custom manufactured specifically for use with CAR-10/CAR-10XH buffers. OEM springs and aftermarket springs (incluging Sprinco Red/Orange/Yellow/Green/Blue/Indigo/Violet) may cause malfunctions. 'Flat-Wire' springs are not recommended for any application.

Note: Not compatible with .223 ARs.
This buffer is designed for use in .308 ARs with a 7" receiver extension (buffer tube). If you have an ArmaLite/VLTOR extended length tube (7-3/4") please see the XH Carbine buffer & .308 Rifle Buffer Spring (EA1095).

I also recommend an XH Carbine buffer & .308 Rifle Buffer Spring (EA1095) for the Magpul UBR Gen2.
