UTG Accu-Sync Spring-Loaded AR15 Flip Up Front Sight

• Spring-loaded flip-up deployment: The sight raises instantly with a push of the release, giving an AR15 a ready backup aiming solution without slowing transitions from optics to irons.
• Standard A2 front sight post: The familiar A2 pattern allows straightforward elevation adjustment and a sight picture many shooters already know, which helps keep zeroing simple and repeatable.
• Low-profile stowed design: When folded, the sight sits at a compact .65 in (16.5 mm) above the rail, so it stays out of the way of magnified optics, red dots, and accessories.
• Secure Picatinny interface: A single locking Torx screw and squared recoil stops help the sight hold zero under regular use and return to the same position after handling or transport.
• Aluminum and steel construction: The combination of 6061-T6 aluminum and steel keeps weight down while preserving the strength needed for a hard-use front sight on a rifle platform.

About the UTG Mounts Series

UTG Mounts covers a broad range of practical mounting solutions and sighting accessories built for modern sporting rifles and general shooting applications. Within this family, the Accu-Sync line focuses on clean fit, dependable rail engagement, and compact dimensions that work well with contemporary optics setups. The series includes Picatinny cantilever mounts, scope rings, and iron sights, with different heights, offsets, and tube-size options across the wider range. That variety makes the platform relevant to everything from lightweight AR builds to more specialized hunting optics and tactical optics configurations.

A consistent theme across the series is a mechanical design that favors straightforward installation and stable alignment on Picatinny rails. In the quick-release variants, Leapers uses locking levers, tool-free tension adjustment, and squared recoil stops, while other Accu-Sync models emphasize low bulk and secure screw-fastened attachment. The result is a product family aimed at shooters who want practical mounting hardware and backup sighting equipment that integrates neatly with modern rifles without adding unnecessary size or weight.

About the UTG Accu-Sync Spring-Loaded AR15 Flip Up Front Sight

The UTG Accu-Sync Spring-Loaded AR15 Flip Up Front Sight is a compact backup iron sight designed for rifles that already carry an optic but still need a dependable mechanical aiming reference. Its spring-loaded, lockable flip-up design lets the sight deploy quickly when needed, while the folded profile keeps the top rail clear during normal use with a red dot, prism sight, or riflescope. That makes it especially useful on AR15 platforms where rail space is limited and sight height must stay compatible with flat-top receiver geometry.

The sight uses a standard elevation-adjustable A2 front sight post, which gives the shooter a familiar adjustment system and a front aiming point that pairs naturally with AR-pattern rear sights. UTG matches that with a center height of 1.42 in (36 mm) over the rail, placing the sight at the standard height for AR-15 flat-top uppers. In practice, this helps maintain proper alignment with same-plane rear sights and supports a conventional iron-sight setup without unusual mounting compromises.

Construction combines 6061-T6 aluminum and steel with a matte black anodized finish, balancing low weight with the rigidity needed for repeated deployment and field handling. The mounting system uses a single locking Torx screw and squared recoil stops to keep the sight firmly seated on a Picatinny rail, which matters for zero retention on a working rifle. At 1.2 oz (34 g) and with a deployed length of 1.12 in (28.44 mm), it adds very little bulk while still providing a full-height front sight solution.

About UTG

UTG is the product brand of Leapers, Inc., a company founded in Michigan in 1992 and headquartered in Livonia, Michigan, United States. Leapers develops optics and shooting accessories for hunting and shooting sports, with a catalog that includes riflescopes, mounts, scope rings, and bipods. The company began with a compact 4×28 scope as its first product, and over time expanded into a much broader range of rifle accessories and sighting equipment.

That background is relevant to products like the Accu-Sync front sight because Leapers has long focused on practical rifle hardware that supports real-world mounting and aiming needs. The company added its UTG PRO line in 2009 for U.S.-made products and established a Taiwan optics research and manufacturing center in 2018, reflecting a continued emphasis on product development across optics and accessory categories.
