Recently, I bought a sight adjustment tool similar to this one:
I can adjust the elevation no problem, but when I go to adjust the windage, I can't seem to figure it out. The pin will move to the left just fine, but not to the right. From what I can tell, when I go to adjust to the right, the tool doesn't line up correctly, and so rather than sliding through the hole, the pin catches.
Does anyone know what I'm doing wrong here. Hopefully I was clear in my description. I'll try and get some pictures up to better show the problem.
