The UTG Accu-Sync 45 Degree Angle Flip-Up Front Sight (brand part no. MT-745) is a Leapers-built offset backup sight designed to sit at a 45-degree angle off a rifle’s main optic, giving a shooter instant iron sights with a simple wrist rotation. It’s a natural fit for AR-platform rifles running a magnified scope or red dot as the primary sighting system, where a fast, reliable backup is needed if the primary optic fails or a close-range target appears. The flip-up design folds flush against the rail when not in use and snaps up cleanly when needed, without interfering with the primary optic’s sight picture. Built for shooters who want a genuine backup, not a compromise.

Key Specifications

• Mounted at a 45-degree offset angle, allowing a quick wrist rotation to bring up iron sights without breaking cheek weld from the primary optic.
• Features a flip-up design that folds flat against the rail when the primary optic is in use and deploys instantly when needed.
• Ships at approximately 0.14 lb, adding minimal weight to a rail-mounted optics setup.
• Built by Leapers’ Accu-Sync line, engineered specifically for reliable offset backup sighting on Picatinny-equipped rifles.
