Ballistic Advantage .750 Low Profile Gas Block – AR-15 Mid-Length & Carbine Systems

This low-profile gas block from Ballistic Advantage replaces standard front sight bases or worn gas blocks on AR-15 platforms using .750" barrel journals. The set-screw design ensures secure mounting under free-float handguards, directing propellant gases reliably into the gas tube for consistent cycling. Shooters upgrade to low-profile blocks to eliminate front sight towers when running optics or to install modern handguards that require a sleek gas block profile.

Machined from steel with a matte black finish, this gas block installs with included set screws that lock against the barrel journal. Installation requires basic gunsmithing tools and knowledge of gas system alignment. The block accepts standard .750" gas tubes for mid-length and carbine gas systems.
