Geissele Super 42 H2 Buffer Spring Combo

Geissele Super 42 H2 Buffer and Spring Combo

The Geissele Super 42 represents a significant upgrade to your AR-15's bolt carrier group cycling system. This combo includes both the innovative braided wire spring and an H2 buffer assembly, delivering a complete solution for improved reliability and performance.

Design Innovation

The Super 42 spring employs a unique three-strand braided wire design inspired by the German MG42 machine gun. Rather than a single coil spring, three independent wire strands work together as a harmonic damper and energy absorber. This design allows each strand to flex independently, effectively dispersing excess energy throughout the system.

Performance Benefits

• 15% stronger average return force compared to standard buffer springs
• Improved reliability with dirty weapons and steel-case ammunition
• Reduced spring fatigue and decreased loss of force over extended round counts
• Eliminates spring twang — the annoying reverberation felt through the buttstock
• Enhanced bolt carrier group cycling for more consistent function

What's Included

This combo provides everything needed for a complete upgrade: the braided wire Super 42 spring and an H2 buffer assembly sized for optimal performance with carbine-length buffer tubes.

Important Compatibility Note

The Super 42 is designed exclusively for carbine-length buffer tubes. It is not compatible with rifle-length or A5 buffer tubes or receiver extensions. Verify your current setup before ordering.

The Bottom Line

If you're serious about AR-15 reliability, the Geissele Super 42 combo is a worthwhile investment that addresses real-world performance issues with a proven engineering solution.
