UTG MNT957 ACCU-SYNC Dual Aperture Flip-Up Rear Iron Sight

The UTG MNT957 ACCU-SYNC rear sight delivers precision iron sight backup with dual aperture functionality for enhanced target acquisition across varying distances. This flip-up design provides reliable secondary sighting when optics fail or batteries die.

What Makes This Different

The ACCU-SYNC system features dual apertures - a large peep hole for close-range rapid target acquisition and a smaller precision aperture for extended distance accuracy. Unlike single-aperture designs, this configuration eliminates the need to swap components or make field adjustments. The spring-loaded flip mechanism deploys instantly under pressure while maintaining zero through repeated use.

Key Features

• Dual aperture design with large and small peep holes for versatile range applications
• Spring-loaded flip-up mechanism with positive lock positions
• Aircraft-grade aluminum construction with Type III hard anodized finish
• Fits standard Picatinny and Weaver rail systems without modification
• Low-profile folded position clears optic sight lines completely
• Tool-free windage adjustment with audible clicks
• Co-witnesses with A2 front sight posts at proper height

Field testing demonstrates consistent point of impact retention through temperature extremes and heavy recoil. The sight maintains zero after thousands of deployment cycles, making it suitable for competitive shooting, law enforcement duty use, and home defense applications. Corrosion-resistant coating withstands saltwater exposure and harsh weather conditions without degradation.
