Ruger FireSight Sight Set — Ruger 10/22 — Black with Fiber-Optic Red Front / Green Rear — Model 90340 (UPC: 736676903405)

Upgrade your Ruger 10/22’s sighting system with the Ruger FireSight Sight Set (Model 90340) — a precision, user-friendly front-and-rear sight package that dramatically improves target acquisition in low-light and daylight conditions. Engineered specifically for the Ruger 10/22 platform, this sight set combines rugged construction, fast visual pickup, and rock-solid repeatability to help you shoot faster and shoot tighter groups with confidence.

Fast Target Acquisition with Dual Fiber-Optic Colors

The Ruger FireSight set uses fiber-optic technology for immediate visual contrast: a red fiber-optic front post for rapid aiming and a green fiber-optic rear for precise alignment. The contrasting red/green combination is deliberately chosen to draw the eye to the front sight while giving a bright, clear reference at the rear—ideal for quick follow-ups, plinking, small-game hunting, and competition. Fiber-optic elements gather ambient light to stay visible without batteries or electronics.

Built for Ruger 10/22 — Direct Fit, No-Hassle Installation

This sight set is designed to fit the Ruger 10/22 receiver without modification. Ruger’s OE-quality fitment ensures the sights mount and index properly for consistent zero retention. Installation is straightforward for anyone comfortable with basic hand tools: remove your factory rear and front sight assemblies, mount the FireSight components to the factory locations, and fine-tune windage and elevation per the included instructions. No gunsmithing is typically required.

Durable Construction & Practical Design

• Material & Finish: Black, corrosion-resistant finish to match Ruger’s factory aesthetics and withstand field use.

• Fiber-Optic Elements: Bright red front / bright green rear — easily visible in varied lighting.
