Geissele Super 42 Buffer Spring Combo H1

Superior AR-15 Reliability Through Innovative Design

The Geissele Super 42 Buffer Spring Combo represents a significant advancement in AR-15 reliability and performance. Inspired by the proven design of the German MG42 machine gun, this system uses three independent braided wire strands instead of a traditional coil spring.

How It Works

The multi-strand design functions as both a harmonic damper and energy absorber. By allowing each strand to flex independently, the spring disperses excess energy more effectively than conventional springs. This reduces the likelihood of spring failure and contributes to more reliable firearm operation across various shooting conditions.

Performance Benefits

• 15% stronger average return force compared to standard buffer springs, improving reliability with dirty weapons and steel-case ammunition
• Eliminates spring twang — the annoying reverberation felt through the buttstock
• Reduced spring fatigue — maintains length and force better than stock springs over extended round counts
• Consistent performance across a wider range of ammunition types and conditions

What's Included

This combo package includes the Super 42 braided wire spring and an H1 buffer assembly, providing everything needed for a complete upgrade.

Important Compatibility Note

This system is designed for standard carbine-length buffer tubes only. It is not compatible with rifle-length or A5 buffer tube/receiver extensions.
