Geissele Super 42 Braided Wire Buffer Spring & H3 Buffer

Description

The Geissele Automatics Super 42 braided wire buffer spring and H3 buffer combo is a carbine-length replacement designed for AR-15 pattern rifles. Its triple-strand braided design functions as a harmonic damper and energy absorber to reduce spring fatigue and the stock “twang” commonly felt by shooters. The set pairs a specially designed spring with an H3 buffer assembly to provide a stronger average return force compared to standard springs. It is intended for shooters seeking improved reliability during routine range use, competition, and duty-type applications.
