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

Extra-Heavy model for suppressed weapons and 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 a 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 AR-15 carbine (collapsible) stock (Magpul/LMT/VLTOR/etc) on your Aero Precision, AR10, SR25, LMT, LWRC, POF or DPMS-pattern .308 AR. 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 reciprocating Tungsten anti-bounce counterweight.

Heavy Buffers reduce felt recoil for the shooter, and minimize wear and tear on the gun. Many customers have reported that installing a CAR-10 XH buffer significantly increased the reliability of their weapon.

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

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

Note: Not compatible with AR-15s!
This buffer is only for use in .308 ARs with a standard 7" deep AR-15 carbine receiver extension (buffer tube).

DO NOT USE A CAR-10 XH buffer in any gun with an A5 buffer tube! Damage/injury/mayhem will result.
If you have an ArmaLite/VLTOR A5 extended length tube (7-5/8"deep) or a Magpul UBR Gen2 stock I recommend an XH Carbine Buffer.

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.
