Troy Industries, Inc. Ar-15 Rear Sight

Rugged, flip-up sights provide failsafe backup when your primary optic or red dot sight fails. Deploys easily and locks securely in place under powerful spring pressure and two locking detent balls, so it can’t be accidentally bumped down until you hit the spring-loaded button on the left side of the base to retract it. Positions apertures at the same height as factory sights, simplifying integration of these sights on your rifle. Base clamps securely to any military or commercial Picatinny rail using a standard flathead screwdriver – no knobs or levers to catch on brush, clothing, or other gear. Protective "ears" shield posts and apertures from impact. Rear sights bolt Mfg: Troy Industries, Inc. SPECS: Stainless steel and aluminum, Black (Blk) or Dark Earth (DkE) finish.
