UTG 45° Rapid Flip-Up Rear Sight for Precision Targeting

Engineered for Precision: AR-15 45 Degree Flip-Up Rear Sight System
Elevate your AR-15’s versatility with this rugged flip-up rear sight system designed for seamless integration with magnified optics. Crafted from aircraft-grade aluminum alloy and treated with a sleek matte black finish, this durable accessory combines military-grade construction with a low-profile aesthetic that blends discreetly into tactical builds. Whether you’re transitioning between optics in dynamic field conditions or relying on backup iron sights during high-stress scenarios, its 45-degree angled offset ensures rapid access without obstructing your primary magnified optic—ideal for shooters prioritizing adaptability in tactical or competitive environments.

The Posi-Lock retention detent mechanism locks the sight tower securely in place during use, eliminating collapse risks even under heavy recoil from high-powered calibers. When folded down, its square-shaped integral recoil stop maintains consistent zero alignment on MIL-STD-1913 Picatinny rails, ensuring reliable return-to-zero performance after adjustments or storage. A single Torx screw simplifies installation while providing unmatched stability against movement or shifting during prolonged use or harsh conditions.

For precise aiming adjustments, the tool-free windage wheel lets you fine-tune your sight picture effortlessly in the field—no tools required—offering quick corrections without disrupting your workflow. Paired seamlessly with the MT-745 flip-up front sight tower (sold separately), this system creates a cohesive backup aiming solution that matches both functionally and visually across your rifle build.

Whether you’re running an AR-15 with an EOTech holographic sight or a Leupold variable optic, this rear sight bridges the gap between modern optical setups and traditional iron sights. Perfect for law enforcement, tactical shooters, or hunters who demand reliability in unpredictable situations, its compact design doesn’t sacrifice strength while enhancing situational awareness during rapid transitions. Backed by precision machining standards, this accessory delivers unmatched durability compared to plastic alternatives while maintaining compatibility across standard Picatinny rail platforms—ensuring your rifle stays ready for action at all times.

Optimize your rifle’s adaptability with an upgrade that prioritizes both performance and practicality under real-world conditions.
