Geissele Super 42 Buffer Spring and Buffer Combo

Geissele Super 42 Buffer Spring and Buffer Combo description - The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 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 AR-15 more reliable.
