Has anyone had any luck modifying ACIS mags of any sort to feed 7.62x39? I've got an extra Magpul hunter stock with the ACIS magwell I'd like to use with my Ruger Ranch Rifle in 7.62x39. I also have an AR mag hunter stock so I know I can use it in that with AR style mags but I'd like to use 10rd ACIS mags if I can figure it out. Hedging my bets against the LAR mags getting banded is part of my reason for wanting to do this but mostly to get some use of the stock I already have.
