Overview
The Geissele Automatics Super 42 Braided Buffer Spring and H2 Buffer is designed as a spring-only assembly that enhances the reliability and performance of your AR-15. Specifically built for a Mil-Spec carbine buffer tube, this combination helps manage recoil and improve cycling, making it ideal for builds utilizing a mid-length gas system in 5.56 NATO caliber. You'll commonly find this setup in precision-focused builds where smooth operation is essential for accuracy and control.
