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.
Geissele Automatics Super 42 Braided Buffer Spring and H2 Buffer was the fourth most added buffer on GunPartPicker in August 2026, behind the Spike's Tactical Spikes Tactical T3 Tungsten Buffer, Black - SLA00T3, with about 9% of all buffers added to builds. That's its 3rd straight month at #4. Builds with this buffer are mostly chambered in 5.56 NATO (77%, then 300 Blackout 14%), split between mid-length (51%) and carbine-length (24%) gas systems, and mostly AR-15 (86%, then AR-10 13%).
It was hard to find in August 2026, in stock on only 3 of the 19 days we checked, and today 3 of the 4 retailers we track have it in stock. It dipped to $87.99 at Sportsmans Outdoor Superstore for a stretch in August 2026, well under its usual $103.12 to $104.18, so sales do come around. Buying today, the lowest price is $89.99 at GritR Sports.

Geissele Super 42 braided buffer spring with H2 buffer drops in to a milspec carbine extension. Braided spring noticeably reduces twang felt through the stock. H2 weight is right for most 5.56 builds. Solid premium recoil system.
