Williams Gun Sight Rifle Rear Sight Blade .188'' U Notch Black

The Williams Gun Sight Rifle Rear Sight Blade in .188″ U Notch is a replacement blade that lets you reconfigure or upgrade your existing Williams rear sight without buying a complete new assembly. Built from high-tensile alloy and milled for precision, this blade swaps into your current Williams sight base, giving you a clean U-notch sight picture for hunting, sport shooting, or general rifle work. It's also compatible with WGRS aperture sights if you want to move away from peep-sight shooting.

The sight blade installs into a dovetailed base with hardened gib locks that hold firm through recoil and rough handling. Windage and elevation adjustments are straightforward—loosen a single screw to make your corrections, then lock it back down. There's no barrel modification needed; the blade works with your existing sight mounting system. Since blades are sold separately from the base, you can keep spares on hand or swap between different notch styles depending on your shooting conditions.

This is genuine Williams Gun Sight gear, backed by the brand's reputation for reliable iron sights on hunting rifles and historical firearms. The rustproof alloy resists corrosion in wet field conditions, and the milled construction means your sight picture stays true shot after shot.

Frequently Asked Questions

Is this a complete rear sight, or just a blade?

This is a blade only. It installs into an existing Williams dovetailed sight base. If you don't have a base, you'll need to purchase one separately.

What rifles does this fit?

This blade fits any rifle with a Williams dovetailed rear sight base. It's widely used on hunting rifles, .22 rimfires, and vintage firearms. Check your current sight base to confirm it accepts a dovetailed blade.

Can I use this blade on a WGRS aperture sight?

Yes. The blade can replace the aperture on WGRS sights, giving you an open U-notch sight picture instead.

Do I need to modify my rifle barrel?

No. The blade uses the existing dovetail on your sight base. No gunsmithing or barrel work is required.
