Not for ar10 308 dpms carbine - KynSHOT AR-10 7.62mm/.308 Recoil Buffer w/ Standard Collapsible Stock

Not for AR10 308 DPMS Carbine Rifles. It does soften the recoil, but it’s too heavy, and the rifle will not cycle. During cycle, it will eject the brass, then jam the new round. I contacted Opticsplanet, and they referred me to the correct buffer that I needed.
