Aero Precision AR-15 H2 Buffer. The H2 Buffer is a heavy buffer designed to reduce felt recoil as well as reduce the cycling rate on full-auto rifles. It is designed to be used with a carbine receiver extension (buffer tube) and spring.
This true mil-spec buffer is AMERICA 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.
