Williams receiver site

Mounted on a Ruger Marlin 1894. If you want a receiver siight it’s the way to go. Well-made, and more accurate than the Buckhorn sites.

Only adjust 3/4 of it's range.

I changed the front sight on my Marlin 336 to an aperture that was .50 inch tall. The Williams came installed with an elevation knob/screw that only adjusts it 3/8" of it's 1/2" total indexed range then the screw comes out. Called Williams and they have a fix (longer screw) for $11 with shipping. I expect any "target" sighting device to be adjustable through it's entire indexed range out of the box or at least information when buying that discloses it's limitations especially when they appear to have photos of the full index marks! I have bought my last Williams product. It would work with the original front sight.
