The PWS Enhanced Steel Body Carbine Buffer in H4 weight is the heaviest buffer from Primary Weapons Systems, at 6.8 oz (brand part no. EBUFFERH4). PWS intends the H4 for suppressed use, where extra reciprocating mass helps tame faster cycling. The body is 4140 steel with a fluted design, and the FNC LIFE HD treatment chemically bonds lubrication into the surface for smoother cycling. It is a tuning part for a carbine that needs more buffer weight.
