So unlike others I have had good luck with Promags AA922 mags in my 10/22. I like the stick look and they function well in my Ruger, as well as you can disassemble them for cleaning. The only thing they were missing is a window to see your round count, because honestly I'm too lazy to count. After a quick inspection I noticed you can take off some of the side material of the mag without hampering its ability to feed so I used one of my old first gen mags to experiment on and here is the result.
Yes they feed just as well after the modification, I used a drill press, a dremel and some sandpaper. Here is some measurements in case your wondering.
1 First gen AA922 mag was harmed in the making of this project.
