Brownells S&W K/L/N Frame .160 V-Notch Sight Kit

The Brownells S&W K/L/N Frame .160 V-Notch Sight Kit upgrades the rear sight on your Smith & Wesson K, L, or N frame revolver with a wider, more defined V-shaped notch that replaces the factory blade. If you shoot a wheel gun regularly—whether at the range, in competition, or afield—you know that a crisp sight picture matters. This kit delivers exactly that by giving your eye a larger, more defined sight notch to align with your front bead or ball sight, cutting down on sight acquisition time when it counts.

The wider V-notch design proves especially useful when you're running finer front sight options, which can otherwise disappear into a narrow factory notch. The kit includes windage adjustment capability, so you can dial in your point of impact once installed. Note that some J-frame models may require a smaller head diameter screw—keep that in mind if you own a compact S&W. The included fastener features a .217" diameter head, sized appropriately for K/L/N frame dovetails.

This is a straightforward, no-frills upgrade for revolver shooters who want faster target acquisition without replacing the entire rear sight assembly. Installation is basic gunsmithing—if you've fitted revolver parts before, you'll handle it easily. If you're new to it, a local gunsmith can have you sorted in minutes.
