The Williams Gun Sight Rifle Rear Sight Blade (Williams part no. 001577) in black uses a .188-inch U-notch design, giving a shooter a replacement blade for a rear sight assembly that’s worn, damaged, or simply needs a different notch style. The U-notch shape opens up visibility around the front sight compared to a square notch, which some shooters find faster to align, particularly on a rifle used for hunting or field shooting where speed matters. As a standalone blade, it’s meant to drop into an existing compatible sight base rather than replace the entire sight assembly. It’s a simple, focused part for anyone restoring or customizing a rifle’s rear sight.

Key Specifications

• Cut with a .188-inch notch width.
• Uses a U-notch blade design for a clean, fast sight reference.
• Finished in black to match a standard rifle rear sight assembly.
