CAR-10-Spring
Description
A CAR-10 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. Standard carbine length stocks cannot be used on these rifles with regular carbine buffers. This is strictly a 'Drop-In' part, no gunsmithing or modifications are required. This product is specifically recommended by Magpul for use with their carbine stocks on .308 ARs. CAR-10 buffers also work great with any other stock using a standard 7" carbine buffer tube. CAR-10 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. Some users have reported that the CAR-10 buffer significantly increased the reliability of their firearms. Note: Not compatible with .223 ARs. This buffer is designed for use in .308 ARs with a 7" receiver extension (buffer tube).
