I bought a set of Warren steel sights to install on my AA .22 conversion kit. As I started to install the rear, apparently it went on a little off-kilter. I don't know why or how, but I definitely wasn't paying enough attention. I guess because the aluminium slide is softer that the steel sight, it made a small gouge in the slide. Enough so, that when I took it out and tried to reinstall it, it falls into that gouge and won't install straight. Hopefully that makes sense. Is there any easy fix for this?
