Geissele Automatics Super 42 H3 Braided Wire Buffer Spring & Buffer Combo - AR-15

The Geissele Automatics Super 42 is a drop-in upgrade for any AR-15 pattern rifle or carbine, pairing a braided-wire buffer spring with an H3 buffer in one ready-to-install combo.

The Super 42 spring is constructed from three independent strands of wire braided together, an innovative design that delivers 15% stronger return force than a standard carbine spring and dramatically reduces spring twang through superior harmonic damping.

Paired with an H3 buffer finished in a low-glare matte finish, this combo is one of the most practical and immediately noticeable function and reliability upgrades available for the AR-15 platform, and installs as a direct replacement for the factory spring and buffer.
