UTG ACCU-SYNC 45° Angle Flip-Up Rear Sight - Matte Black

The UTG ACCU-SYNC 45° angle flip-up rear sight is a no-nonsense offset iron sight built for shooters who run magnified optics and want reliable backup aiming capability without sacrificing primary scope placement. Machined from aircraft aluminum and finished in matte black, this sight mounts at a 45-degree angle to your rail—positioning it completely clear of your primary magnified optic while remaining instantly accessible when you need to transition to iron sights. Whether you're setting up a precision rifle, a patrol carbine, or a competition build, a quality offset rear iron keeps you combat-ready if your primary system fails.

The 45-degree offset geometry is the tactical standard: your sight rides perpendicular to your main optic's line of sight, so you can flip it up and acquire targets without removing or replacing your primary glass. The aircraft aluminum construction keeps weight minimal while delivering the rigidity needed for reliable zero retention through hard use. The matte black finish resists glare and blends seamlessly with modern tactical rifles and carbines.

UTG (made by Leapers, Inc.) has earned solid reputation for producing functional, affordable backup iron sights and accessories. This sight is built for the shooter who understands that redundancy saves lives—your rifle's primary optic can fail, fog, or get damaged, and when it does, a proven offset rear iron is your insurance policy. Run it with your favorite primary scope and trust it as a serious, not theoretical, backup.

Frequently Asked Questions

What rail system does this offset rear sight fit?

This sight is designed to mount on standard Picatinny rails. Confirm your platform uses a full-length Picatinny rail before ordering.

Will this rear sight work with a magnified scope on the same rifle?

Yes—that's exactly what it's designed for. The 45-degree offset positions the rear sight completely out of the way of your primary optic, so both can coexist on the same rifle without interference. When you need irons, flip it up; when you're using your scope, it stays low and out of sight.

Can I use this as my primary rear sight without a magnified optic?

Technically yes, but it's engineered as a backup. The offset angle is optimized for co-witnessing with a 45-degree mounted optic or for rapid transitions when your primary sight system fails. For a dedicated irons-only setup, a traditional rear sight mounted directly to the receiver or upper will be more ergonomic.

Is this sight zeroed when it arrives?

No—all iron sights require zeroing to your rifle before relying on them in the field. Once mounted and zeroed, the POSI-LOCK system is designed to hold that zero through normal shooting and handling.
