Super 42 Braided Wire Buffer Spring / H2 Buffer Combo Accessory especially the lighter chassis suchThe Geissele Super 42 Buffer Spring Buffer Combo was designed to improve the function and reliability of your AR 15 pattern rifle. Its unique spring design uses three independent strands of wire. 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.
