Rugged, flip-up sights provide failsafe backup when your primary optic or red dot sight fails. Sight body flips up easily when you need it 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 protruding knobs or levers to catch on brush, clothing, or other equipment. Sturdy, protective "ears" shiel Mfg: Troy Industries, Inc. SPECS: Stainless steel and aluminum, Black or Dark Earth finish.
