I have a slight case of jamming plaguing my Mini-14. I think most of my hi-caps are USA mags, which could be part of the problem. At one point, I thought it might need a good cleaning, but even after I did so it still jammed (though admittedly not as bad). Any suggestions what I can do to alieviate this problem? Would replacing the magazine followers with Ruger factory mag followers (as I've seen suggested elsewhere on this board) help matters much?
