In this informative video Bill Geissele not only introduces but explains what drove the development of his new Super 42 Braided Wire Buffer Spring Kit for the AR series of rifles. He states his new braided wire spring was designed to improve both the performance and reliability compared to a standard round spring. Geissele’s website states, “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.”
As the inner diameter of Geissele’s new spring is smaller than a standard spring the kit includes an H weight buffer. Price on the kit is $59. Check out what Bill has to say. If you take the time to watch this video you’ll learn a lot about buffer springs and how they operate.
