Original Patented Buffer Upgrade Kit featuring Custom Buffer and Braided MG42 German Machine Gun Design to absorb the energy of rapid fire with virtually no spring noise!
The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.
Compared to the stock spring, The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock. The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.
NOTE: The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions. We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.
The Super 42 spring and Geissele buffer are designed to work together as a set; the spring will not fit over a standard buffer. If installed with a standard buffer damage to the rifle or receiver extension will occur.
Please refer to the Quick Reference Table for common balancing weights based on use with Mil-Spec AR15 / M4’s chambered in 5.56 in the product gallery or download "Product Guide" under the Resources Section, below.
Barrel length, gas system, ammunition and manufacturer’s specifications for build parts will largely affect the outcome. Further testing with preferred ammunition and buffer weights may be necessary to completely dial in a build.
