Geissele Super 42 Braided Wire Buffer Spring & H1 Buffer Combo – 05-495

The Geissele Super 42 H1 Combo (UPC: 854014005908) is the foundational upgrade in Geissele's recoil management line, designed to enhance the reliability and shooting experience of any standard AR-15. Inspired by the recoil system of the German MG42 machine gun, the Super 42 spring features a triple-strand braided wire design. Each strand of wire flexes independently, acting as a harmonic damper that absorbs excess energy and virtually eliminates the "cheese grater" twang and vibration commonly heard through the buttstock with mil-spec springs. With a return force approximately 15% stronger than standard springs, it ensures more consistent chambering and stripping of rounds, even in extremely dirty rifles.

This H1 variant is the standard "Heavy" setup, featuring one tungsten weight and two steel weights. It is the ideal upgrade for 16-inch carbines with carbine-length gas systems or 14.5-inch builds that need just enough extra mass to smooth out the cycling without compromising reliability with lower-powered range ammunition. Because the Super 42 spring has a smaller internal diameter to accommodate its braided structure, it is a matched set and will not fit over a standard mil-spec buffer. Precision-manufactured in North Wales, Pennsylvania, the 05-495 kit is the most cost-effective way to achieve a "tuned" feel in a duty-ready rifle in 2026.

Includes: (1) Super 42 Braided Wire Buffer Spring and (1) Geissele H1 Heavy Buffer.

Key Features

• Triple-Strand Braided Design: Proven MG42-style architecture dampens harmonics and prevents the spring from losing its "set" or length over tens of thousands of rounds.
• H1 Heavy Weight: Perfectly balanced with one tungsten weight to slow the bolt carrier group just enough to reduce wear and felt recoil on standard rifles.
• Assisted Feeding: The 15% increase in return force helps the bolt overcome friction from carbon buildup or high-friction steel-cased ammo.
• Silent Operation: Significantly reduces the resonance and mechanical noise transmitted through the receiver extension during fire.
• Duty-Grade Materials: Uses high-tensile chrome silicon steel for the spring and premium tungsten/steel components for the buffer.
• USA Made: Every kit is built to the rigorous quality standards Geissele is known for across the defense industry.
