I also use accurate mags. This is what the Cadex rifles come with. So pleanty of good options. The Magpul mags on my 300 wm don't work very well have to sand the top down a bit as the feed lips are too tall and won't let the mag seat fully. Just what I found. No idea if it's the same on the SA guns.I used Magpul AI and Alpha mags without any issues. I think they should run any of the mags available.
