The Geissele Automatics Super 42 Braided Wire Buffer Spring features a unique three-strand braided design similar to the legendary German MG42 machine gun. This arrangement allows for better energy absorption and harmonic dampening by allowing the springs to flex separately against each other, increasing the reliability and improving the function of your AR-15.


  • Rifle length
  • Designed after the MG42 machine gun recoil spring
  • Provides a longer spring life and more reliable function
  • Triple-strand braided wire
  • Dampens harmonics
  • Superior energy absorption

For use with AR-15 rifle receiver extensions only, will not work with A5 length or carbine length extensions.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.

Unique product with wrong description

by -

The last line of the product description say it comes with a buffer but in the picture there is none. I'm assuming that the price of $25 means it is without the buffer and the description is wrong.

Super 42 Rifle Length Spring

This is for Rifle length buffer tubes only. No Buffer is included. The braided spring has been used since WW2 in military arms. The Germans and Russians all use the braided springs in firearms. Now I have one for my AR MK 12/Mod 0.
