Geissele Automatics 05495H3 Super 42 H3 Buffer, Braided Wire Spring, Carbine Length for AR-15

Overview

The Geissele Super 42 H3 Buffer and Carbine Length Spring assembly is designed to significantly enhance the function, reliability, and smoothness of an AR-15 pattern rifle. Utilizing a unique braided wire design inspired by the German MG42 machine gun, the spring incorporates three independent strands of wire that flex separately to act as a harmonic damper and energy absorber. This configuration helps displace excess energy, reduces the likelihood of spring failure, and eliminates annoying spring reverberations and twang through the buttstock. The Super 42 spring provides a 15% stronger average return force compared to standard buffer springs, aiding in reliable feeding when operating with dirty firearms or steel-cased ammunition. Paired with a heavier H3 buffer, this system slows the bolt carrier to tame over-gassed and suppressed rifles, delivering a flatter and quieter recoil impulse. It is intended for use with carbine-length buffer tubes and receiver extensions.
