We believe the A5 System is the best buffer system on the market and our kit makes it even better with the inclusion of a Sprinco Green Spring, FCD CNF castle nut, and B5 Systems End plate. The A5 system increases lock time and decreases felt recoil with the use of a rifle length spring, and an internally spring biased buffer weight stack. Multiple buffer weights are available, however we default to the A5H2 buffer.
