Wilson Combat TRQDSR Flip-Up Rear Sight Black AR-15 Backup BUIS

The Wilson Combat TRQDSR rear sight delivers precision backup sighting capability when your primary optic fails. This flip-up design maintains a low profile until needed, then deploys instantly for accurate target engagement at standard AR-15 sight radius distances.

What Makes This Different

Unlike basic polymer backup sights, the TRQDSR features Wilson Combat's precision machining and robust construction standards. The sight body incorporates hardened steel components where stress concentrations occur, while maintaining lightweight aluminum construction elsewhere. Spring-loaded detents provide positive indexing in both folded and deployed positions, eliminating the wobble common in budget alternatives.

Key Features

• Precision-machined aluminum construction with hardened steel wear surfaces
• Spring-loaded detent system for secure folded and deployed positioning
• Standard A2-style rear aperture for familiar sight picture
• Low-profile folded height clears most optic mounts and accessories
• Tool-free windage adjustment with positive click detents
• Matte black hard anodized finish resists corrosion and wear
• Direct attachment to Picatinny rail systems without adapters

Field performance remains consistent across temperature extremes and environmental conditions. The sight maintains zero through repeated folding cycles, making it suitable for competition use where backup sights see frequent deployment. Law enforcement and military users benefit from the tool-free windage adjustment system that allows precise zeroing without removing the rifle from service. The hardened aperture edges resist deformation from impact or rough handling.
