Geissele Super 42 Braided Wire Buffer & H2 Buffer — Carbine

Description

The Geissele Super 42 is a braided-wire buffer spring and H2 buffer combo engineered for AR-15/M4 platforms using carbine-length buffer tubes. Its three-strand braided design reduces harmonic reverberation and spreads energy across independent strands, which mitigates spring failure and length loss over time. The Super 42 offers a higher average return force than a standard buffer spring, aiding reliable cartridge strip and cycling under adverse conditions. Note that this set is intended for carbine-length receiver extensions and is not compatible with rifle-length or A5 buffer tubes.
