["Flip up iron sights designed as backup iron sights for Picatinny rail systems.","Built for Durability and Strength – Sight Screw Torque 22.5 inch pounds - Sights are intentionally stiff out of the box to ensure a secure, no-wiggle fit. With use, deployment becomes smoother while maintaining rock-solid retention, even under heavy recoil from high-caliber or 5.56 rifles. For easiest installation, open the sights and slide them onto the rail from the rear where the base is slightly wider, using the rail for leverage. A small drop of oil can help ease initial movement.","Durable Lightweight Design – Manufactured using high-impact, fiber-reinforced polymer for long-lasting performance in demanding conditions.","Complete Flip-Up Sights: Includes both front and rear backup sights, designed for standard Mil-Spec 1913 Picatinny rail systems.","Low-profile when folded to reduce snag and profile.","Quick Deploy Flip-Up Mechanism – Dual-side activation with positive detent locking in both up and down positions; folds flat to stay out of the way.","Precision-Adjustable – Front sight features indexed elevation drum; rear sight includes ambidextrous windage adjustment (0.5 MOA per click) for consistent and accurate zeroing.","MANUAL FLIP-UP DEPLOYMENT – Non-spring-loaded folding design provides controlled deployment, dependable lockup, and reduced moving parts for long-term reliability."]
