Enhance the performance and reliability of your AR-15 with the Geissele Super 42 Braided Wire Buffer Spring and Buffer Combo. Featuring a unique design inspired by the German MG42 Machine Gun, this buffer spring uses three independent strands of wire that flex separately, acting as harmonic dampers and energy absorbers. This innovative concept helps displace excess energy, reducing the risk of spring failure and significantly enhancing the reliability of your AR-15. Unlike standard buffer springs, the Geissele Super 42 maintains its length and force, even after extensive use. Say goodbye to the annoying spring reverberations, or "twang", as this combo eliminates those disturbances, providing a smoother shooting experience. With a 15% stronger average return force than conventional springs, it excels at stripping rounds from the magazine, ensuring dependable operation even in dirty conditions or when using steel-case ammunition. Please note that the Geissele Super 42 is designed for use with carbine-length buffer tubes and is not compatible with rifle-length or A5 buffer tubes. Additionally, it is not recommended for use with 300 Blackout subsonic ammunition, as the spring's powerful performance may impact the rifle's functionality. Upgrade your AR-15 today with the Geissele Super 42 Braided Wire Buffer Spring and Buffer Combo for superior reliability and performance.
