Geissele Super Gas Block Black .750″ (05‑807B) is a low-profile, precision gas block engineered to fit under most free-floating AR‑15 and AR‑10 rails. Cast from 17‑4 precipitation‑hardening stainless steel and finished in black nitride, this block is built for long-term corrosion resistance and rugged reliability. It supports Geissele’s “bombproof” installation method using a coil pin, ensuring the block never shifts under recoil, and includes a stainless steel alignment pin for perfect indexing on CHF barrels.
