Aero Precision AR-10 / 308 Carbine Buffer
M5 .308 Carbine Buffer for use in .308 Carbines with a .308 Carbine Receiver Extension (buffer tube). This shorter .308 buffer is specific to .308 Carbines and will not work in .308 Rifles or AR15 platform firearms.
This true mil-spec buffer is American Made and features three separate weights which adds reciprocating mass to the buffer and prevents bolt bounce. The same can't be said for many inexpensive buffers on the market today which have only a single solid weight.
