Easy to See, Easy to Install
Featuring a precision CNC-machined steel front sight with a fiber optic insert, XS Fiber Optic sights were designed for fast sight acquisition, precise sight alignment, and easy installation.
These pinned revolver sights feature a pre-drilled pinhole for easy DIY installation. No custom gunsmithing is needed! Simply drive out the factory pin, remove the sight, install ours, and drive the pin back in place.
Improve your accuracy and sight acquisition speed with a precision sight picture. Ramp sights make precision shots difficult because setting the elevation repeatedly and quickly is hard. Our wide notch, serrated rear, and fiber optic front sight provide a high-contrast sight picture in bright light. The combination increases front-sight acquisition speed and provides a clearer downrange view of the target.
Want a Fixed or Adjustable rear? You've got options.
If you're looking for a durable, long-lasting solution for your adjustable rear-sight revolver, consider upgrading your Smith & Wesson revolver with fixed sights that won’t shift. You can easily replace the adjustable rear sight on your Smith & Wesson with a rugged fixed rear sight through our simple DIY replacement process.
Do you need windage adjustments to achieve your perfect Point of Impact (POI) and Point of Aim (POA)? If so, the serrated adjustable rear sight option may be ideal for you. This sight offers fine-tuning capabilities that allow you to make precise adjustments to better align your sights with your intended target.
Both options offer our proven sight picture, with an easy-to-see front sight paired with a serrated rear design that helps reduce glare, making it easier to focus your aim, especially in bright conditions.
