Awesome, but... - Williams Gun Sight Ruger American .22LR Target FP Rear Sight

This rear aperture sight is awesome, but finding a good front sight to match was for me almost impossible. I didn't like Williams' matching front globe sight. I prefer a fiber-optic blade front sight, but there aren't too many made tall enough to work with this rear sight. I ended up having to modify one meant for a different gun, and that works great now.

So, I'm very happy with the rear sight. It helps my aging eyes keep up with my son without using a scope. The 20" & 22" RARs are excellent platforms for aperture sights too.
