Geissele Automatics 05495H3 Super 42 H3 Buffer Braided Wire Spring Carbine Length for AR15

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR15 pattern rifle. Its unique spring design uses three independent strands of wire just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR15 more reliable. Compared to the stock spring The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus it removes the annoying spring reverberations twang heard and felt by the shooter through the buttstock. The Super 42 Spring has a 15 stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steelcase ammo. NOTE The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubesreceiver extensions
