Williams Gun Sight Rifle Rear Sight Blade .250'' U Notch Black

The Williams Gun Sight Rifle Rear Sight Blade in .250" U Notch is a direct replacement blade for shooters who want to upgrade or repair their iron sight setup. Williams has been building dependable rifle sights since 1932, and this blade carries that reputation for precision and durability. If you're running Williams Gun Sight rear sights or WGRS sights and need a fresh blade—whether from wear, damage, or simply preferring a different notch style—this .250" U Notch blade drops in as a straightforward swap.

This blade is milled from high-tensile strength, rustproof alloy, so it resists corrosion in wet conditions and holds up to the hard use that hunting and range work demand. The blade integrates with dovetailed windage and elevation adjustments secured by hardened gib locks, allowing you to dial in your sight picture with confidence. Adjustments are fast and intuitive—just loosen a single screw to make your changes, no gunsmithing required. Because Williams sights mount directly to the barrel or receiver without requiring dovetail cuts to the barrel itself, installation and blade swaps are accessible to any shooter with basic tools.

The U Notch profile is a classic choice for hunting and practical shooting, offering a good balance between light gathering and precision. Keep a spare blade in your shooting kit, or swap blades to match different ammunition loads or shooting distances.
