HiViz SW617G Green Fiber Optic Front Sight Smith & Wesson 617 647 648

The HiViz SW617G transforms target acquisition on Smith & Wesson K-frame revolvers with its bright green fiber optic technology. This precision-engineered front sight replacement delivers faster sight alignment and improved accuracy across varying light conditions.

What Makes This Different

Unlike standard black front sights that disappear in low light, the SW617G utilizes a high-grade fiber optic rod that gathers ambient light to create a brilliant green aiming point. The sight body is machined from aircraft-grade aluminum with a matte black finish that eliminates glare. Installation requires no gunsmithing - the sight drops into the factory dovetail and secures with the included set screw.

Key Features

• Bright green fiber optic rod for rapid target acquisition in all lighting conditions
• Direct replacement for factory front sight on S&W 617, 647, and 648 revolvers
• Aircraft-grade aluminum construction with corrosion-resistant black finish
• Standard dovetail fitment - no permanent modifications required
• Protective sight hood shields fiber optic from impact damage
• Includes replacement fiber optic rods and installation hardware
• Height matches factory sight for maintained zero with existing rear sight

Competitive shooters and hunters appreciate the SW617G's ability to maintain consistent sight picture from bright outdoor ranges to dimly lit indoor facilities. The green fiber optic provides excellent contrast against most target backgrounds while remaining visible in challenging dawn and dusk conditions. The reinforced sight hood protects the delicate fiber optic element during transport and field use.
