One-Piece Design Fits Under Free-Float Handguards

Slim replacement for cumbersome USGI front sight/gas block tower features a low profile for a more streamlined appearance and less chance of snagging on vegetation and other gear. Covers only 1" of barrel length and reduces weapon’s forward weight for improved handling and maneuverability. Clamp On models squeeze around the barrel with included socket head screws. Set Screw models use included set screws at the bottom of the unit to anchor the gas block to the barrel for the lowest-profile installation.
