Not suited to the recommended front sight - Williams Gun Sight Ruger American .22LR Target FP Rear Sight

Nicely made and apparently designed to use with the Williams front sight (WL-RS1-RA22LRTAB-71079) on the Ruger American Rimfire. Unfortunately this front sight / rear sight combination doesn't work because the front sight tube diameter is too large and the rear sight is necessarily mounted too far forward. To make it work on my rifle the rear sight aperture would have to be the same size as the threaded hole the eye piece screws in to. I really wanted to like this set up and have several Williams sights but unfortunately for me I wasted my money. Williams - you need to design a smaller diameter front sight to pair with this rear sight and I would buy it.
