World of Geissele

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.

Bill Geissele and the executive team led us in signing the very first shipment of the USSOCOM MRGG-S. From design to engineering to assembly to shipping, every department played a crucial role in this project. All teammates had the opportunity to sign their name and a leave a special note on one of the first MK1 MOD0's heading out to our troops! #Geissele #MRGG
