UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight

The UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight is a premium backup iron sight designed to provide dependable aiming performance when your primary optic is unavailable. Built for AR-15, AR-10, and other rifles equipped with MIL-STD 1913 Picatinny rails, this rear sight deploys instantly with a spring-loaded push-button system, giving shooters a fast and reliable backup aiming solution.

Precision CNC machined from 6061-T6 aluminium and steel, the UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight combines lightweight construction with exceptional durability. Its compact fold-over design occupies minimal rail space while maintaining a low profile when folded, making it an excellent choice for rifles equipped with red dots, LPVOs, or magnified optics.

UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight Features

The UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight features a spring-loaded deployment system activated by a positive-lock push button.

With a single press, the sight automatically deploys into position and locks securely in place. As a result, the sight remains stable during firing and resists accidental collapse under recoil.

Dual Aperture for Versatile Shooting

The rear sight incorporates a dual-aperture design, allowing shooters to switch quickly between apertures for different target distances and lighting conditions.

In addition, the tool-free windage adjustment wheel makes sighting-in fast and convenient, enabling precise adjustments without the need for extra tools.

Secure Picatinny Rail Mount

The UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight mounts directly to MIL-STD 1913 Picatinny rails using a single Torx locking screw.

Furthermore, integrated square recoil stops provide a secure hold under repeated recoil while maintaining excellent return-to-zero performance if the sight is removed and reinstalled.

Low-Profile and Lightweight Design

Designed to maximise rail space, the UTG ACCU-SYNC Spring Loaded Rear Flip-Up Sight folds down to a compact 0.68-inch stowed height.

Despite its rugged construction, the sight weighs only 1.4 ounces, helping reduce overall rifle weight without compromising strength or reliability.

For a complete backup iron sight system, pair this rear sight with the UTG ACCU-SYNC Spring Loaded Front Sight (MNT-757).
