The correct buffer weight depends on many variables - your buffer tube length (carbine or rifle length), gas system length, the gas port size, spring,ammunition, and if a suppressor will be used.

AR-15 carbine H3 buffers are direct swaps for Armalite AR-10 carbine buffers - the size and weight are identical. DPMS LR-308 carbine buffers are lighter, and will benefit from an AR-15 H3 carbine buffer.
