Geissele Super 42 Braided Wire Buffer Spring & H1 Buffer Combo

Description

The Geissele Super 42 Braided Wire Buffer Spring and H1 Buffer Combo is a replacement spring and matched buffer assembly designed for AR-15 pattern rifles using carbine-length buffer tubes. Its braided three-strand spring design acts as a harmonic damper and energy absorber by allowing the wires to flex independently, which reduces spring reverberation and decreases the likelihood of spring failure over time. The assembly includes a Geissele H1 buffer and is intended to work as a set; the spring will not fit over a standard buffer and requires the supplied buffer for proper installation. This combo is listed as having a stronger average return force compared to a standard buffer spring, which can assist with reliable feeding in adverse conditions.

As a matched spring-and-buffer solution, the Super 42 combo offers a durable option for shooters looking to reduce spring twang and support more consistent cycling in carbine-length AR-15 setups. Its braided construction and stronger return force make it a practical upgrade for owners who prioritize reliable operation and reduced stock vibration without changing other system components.
