Geiselle Super 42 Braided Spring and Buffer

The Geissele Super 42 Spring is designed to increase the function and reliability of your AR-15 rifle. Modeled after the innovative spring system of the German MG42 machine gun, this spring uses three independent wire strands to act as a harmonic damper and energy absorber. The separate flexing of each strand helps dissipate excess energy, reducing the risk of spring failure and improving overall reliability.

Key Features:

• Harmonic Damper Design: The unique three-strand design reduces the chance of spring failure by absorbing and displacing excess energy.
• Increased Reliability: The Super 42 Spring has a 15% stronger average return force compared to standard buffer springs, aiding in stripping rounds from the magazine—especially when operating in dirty conditions or using steel-case ammo.
• Durable Construction: Engineered to retain length and force over time, offering superior longevity compared to stock springs.
• Quieter Operation: Eliminates the “twang” sound often heard and felt through the buttstock, providing a smoother shooting experience.

Important Notes:

• Compatibility: Designed for use with carbine-length buffer tubes. Not compatible with rifle-length or A5 buffer tubes.
• 300 Blackout Warning: Not recommended for use with subsonic 300 Blackout ammunition, as the spring may be too strong to allow proper rifle function.

Upgrade your AR-15 with the Geissele Super 42 Spring for enhanced performance, durability, and a smoother shooting experience.
