Geissele Automatics AR 15 Super Gas Block – .750 Diameter

Bomb-Proof Your Gas System

Geissele’s Super Gas Block comes included with their renowned Super Modular Rails – but this level of quality isn’t just for the Geissele build.  With tight tolerances, and extra-sturdy coiled roll pins, this gas block can be installed with set screws, or pinned to the barrel for a hold that never fail.  The last part definitely takes the right equipment and know-how, but for seasoned professionals or serious hobbyists, it’s a definite must.

Available in Stainless Steel or Black Nitride.
