Overview
Built for AR-15 style firearms, this low-profile gas block is aimed at shooters who want a lighter setup without adding unnecessary bulk under the handguard. Its titanium construction and compact form make it a practical choice where space is limited, while the two set screw design is intended to provide a secure installation. The bead blasted matte finish gives it a subdued appearance, and the .625 or .750 internal bore options allow it to fit the specified barrel setup. Blue locking compound and a dimpled barrel are recommended for installation, so it is best suited to users comfortable with a more deliberate build process.
