Geissele AR-15 Super 42 Braided Wire Buffer Spring/Buffer Combo Kit For Carbine Receiver Extensions H1 Buffer Weight

Overview

The Geissele Super 42 buffer and spring combo is designed to improve the function, reliability, and lifespan of AR-15 pattern rifles. Utilizing a unique spring design modeled after the German MG42 machine gun with three independent strands of wire, it acts as a harmonic damper and energy absorber to flex separately and displace excess energy. This design reduces spring failure rates, helps strip rounds reliably when using steel-case ammunition or a dirty weapon, and eliminates spring reverberation twang. The spring features a 15% stronger average return force than standard buffer springs, though it is not compatible with rifle-length or A5 buffer tubes or recommended for use with 300 Blackout subsonic ammunition.
