UTG ACCU-SYNC 45 Degree Angle Flip Up Rear Sight

The UTG ACCU-SYNC 45 Degree Angle Flip Up Rear Sight by Leapers Inc. is a compact, quick-deploy aiming solution designed for modern tactical rifles and carbines. This flip-up rear sight mounts directly to Picatinny rails and enables rapid target acquisition by rotating into place when secondary or backup aiming is needed. The 45-degree mounting angle positions the sight for co-witness or lower-third co-witness with magnified optics, allowing shooters to transition between primary scopes and iron backup without removing the rifle from firing position.

The ACCU-SYNC design integrates a precision aperture and windage adjustment mechanism, allowing fine-tuning of point of aim once deployed. At 0.15 lbs and measuring 2.85 x 1.5 x 4.2 inches when folded, the sight adds minimal weight and profile to your setup. The flip-up configuration stores flat against the rail when not in use, reducing snag points during movement through tight spaces—a critical consideration in close-quarters or dynamic shooting environments. The Picatinny interface ensures repeatable mounting across multiple rifles without compatibility concerns.

This sight appeals to shooters building multi-optic systems—those running magnified primary optics who require a reliable secondary aiming method. Law enforcement, military training, and civilian tactical practitioners rely on backup iron sights to maintain capability if primary optics fail or become obscured. The 45-degree flip-up mounting allows this rear sight to coexist with red-dot sights, prismatic scopes, and variable-power optics without creating sight alignment conflicts. Leapers' UTG line is established in the tactical accessory market for delivering functional solutions at accessible price points.
