UTG Accu-Sync Flip-Up Front Sight for AR-15 - Black Backup Iron Sight (MNT755)

The UTG Accu-Sync flip-up front sight for AR-15 is a low-profile backup iron sight built to work alongside your optics or function as a standalone aiming solution. Made from precision-machined aircraft-grade aluminum with an anodized finish, this Leapers UTG sight mounts directly to your Picatinny rail and flips up or down as needed. It's the kind of no-fuss backup sight that AR-15 shooters rely on when they want a dependable iron sight that stays out of the way until it matters.

What sets this sight apart is the Posi-Lock design with a side plunger release—it locks solid when deployed and releases cleanly when you need to fold it down. The front sight post is elevation adjustable using a standard 4-prong front sight adjustment tool, giving you the ability to dial in your zero without aftermarket tools or gunsmithing. The slim profile keeps it from interfering with co-witnessed optics or adding bulk to your upper receiver.

Whether you're running a red dot with a magnifier, a scope, or going iron-only, the Accu-Sync delivers the rugged simplicity AR shooters have come to expect from UTG. It's purpose-built for the AR platform and works equally well on other long gun applications with Picatinny rail systems.

Frequently Asked Questions

Will this flip-up front sight work with my red dot or scope?

Yes. The low-profile design is meant to work alongside optics mounted on the Picatinny rail. You can run it co-witnessed with a red dot, use it as a backup under a magnified optic, or fold it down to keep it completely out of your line of sight.

Is the Posi-Lock secure enough for field use?

The Posi-Lock design with side plunger release is engineered to hold the sight securely in the deployed position and maintain zero retention. Once locked, it stays put; the plunger release makes it easy to fold down when needed.

Can I adjust the elevation myself?

Yes. The front sight post is elevation adjustable using a standard 4-prong front sight adjustment tool, which allows you to dial in your zero without special equipment.

What rails does this mount to?

This sight mounts to standard Picatinny rails. It's designed for AR-15 uppers and other long gun platforms equipped with Picatinny rail systems.
