The Geissele Automatics Super 42 Braided Wire Buffer Spring and H2 Buffer Kit for AR-15 is a buffer tube that fits AR-15.
The 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. 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 Percent 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 steel-case ammo. Not compatible with Rifle Length or A5 Buffer Tubes/Receiver Extensions. Includes an H2 buffer assembly.
The buffer tube (receiver extension), buffer and spring control how an AR-15 cycles and also carry the stock. Check the tube diameter (mil-spec or commercial) and length against your stock and rifle before ordering.
