Enhance the performance and reliability of your AR15 with the Geissele Automatics Super 42 Carbine Buffer Spring H2. Crafted with a unique braided wire design inspired by the German MG42 machine gun this spring features three independent strands that work together to absorb energy and dampen vibrations. This innovative construction reduces the risk of spring failure and minimizes the annoying twang often felt through the buttstock. With a 15% stronger return force than standard springs the Super 42 excels in challenging conditions ensuring smooth operation even with steel case ammo or when your weapon is dirty. Specifically designed for carbine-length buffer tubes this spring offers a robust solution for improved firearm function.
