Clamp-on 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. Machined from high-grade 4140 carbon steel to precise tolerances to fit on barrels with a .750" O.D. at gas block mounting position. Hard, manganese phosphate Parkerized finish adds strength and resists surface abrasion; matches most factory barrels. Will not fit under small diameter freefloat handguards or some models with an exposed bottom rail channel on the inside of the handguard.
SPECS: 4140 carbon steel, Parkerized, matte black. Includes hex-head mounting bolts and gas tube pin. Fits AR-15/M16 with .750” O.D. barrel at gas block position. Will not fit under small diameter freefloat tubes or those with an exposed bottom rail channel on the inside of the handguard such as the VLTOR VIS and models manufactured by Daniel Defense and LaRue Tactical.
