Geissele Super 42 Spring

Inspired by the German MG42 Machine Gun, the Geissele Super 42 Spring uses three independent wire strands to improve reliability and performance. Its unique design acts as a harmonic damper and energy absorber, displacing excess energy and reducing spring failure.

Enhanced Performance

• Reliability: Reduces the tendency to lose length and force over extended use.
• Reduced Noise: Eliminates spring reverberations (twang) felt through the buttstock.
• Stronger Return Force: 15% stronger average return force compared to a standard buffer spring.
• Improved Functionality: Assists in stripping rounds from magazines under dirty conditions or with steel-case ammo.
