Geissele Automatics Super Gas Block .750" Steel Black Nitride for AR Platform

The Geissele Automatics Super Gas Block is a precision-engineered, low-profile .750" gas block purpose-built for AR-15, AR-10, and M4 pattern rifles. The bore is machined to closely fit the .750" diameter mounting bosses found on most modern AR-platform barrels, and the slim low-profile silhouette allows the block to tuck neatly under the vast majority of free-float handguards on the market.

Investment cast from 17-4 precipitation hardening stainless steel, the Super Gas Block delivers the strength and dimensional stability expected from a duty-grade component, and it is finished in a deep, corrosion-resistant Black Nitride coating for a long service life. Compatible with 5.56x45mm NATO and .223 Remington chambers, the Geissele Super Gas Block is a clean, reliable upgrade or replacement for any AR-platform build where a low-profile, low-maintenance gas block is desired.
