Upgrade the reliability and cycling performance of your AR-15 with the Geissele Super 42® Braided Wire Buffer Spring and H3 Buffer Combo. Engineered as a complete system, the Super 42 combines Geissele's innovative braided wire spring design with a matched H3 buffer to deliver smoother operation, enhanced durability, and improved reliability under demanding conditions.

Inspired by the proven spring technology used in the legendary German MG42 machine gun, the Super 42 utilizes three independent braided wire strands that act as a harmonic damper and energy absorber. This unique construction reduces spring fatigue, minimizes the annoying buffer spring "twang," and provides approximately 15% greater return force than a standard AR-15 carbine buffer spring.

The increased return force improves feeding reliability by helping strip rounds from the magazine more consistently, especially when the rifle is dirty or when using steel-cased ammunition. Combined with the included H3 buffer, the system delivers smoother recoil impulse and reliable function for properly tuned AR-15 carbines.

The Super 42 Spring and Geissele H3 Buffer are specifically engineered to function together as a matched set. Because of the proprietary braided spring design, the Super 42 spring is not compatible with standard AR-15 buffers, and using it with a standard buffer may damage the firearm or receiver extension.

Whether you're building a duty rifle, competition gun, or dependable defensive carbine, the Geissele Super 42 Braided Wire Buffer Spring and H3 Buffer Combo delivers the enhanced performance, reliability, and longevity expected from one of the industry's most trusted manufacturers.
