Troy Industries Rear Backup Iron Sight for AR-15

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 to flattop receiver rail and are only .460" high when folded. Detent-locking adjustment wheel lets you change the windage setting in ½ MOA increments.
