I have 308, and 300WM Alpha mags, as well as AI mags in each of those calibers (the 308 is switched between 308 and 6.5CM). For some reason I like the Alpha mag finish better, but I don't think that's a decision point worth considering. I see them both as high quality and I value them equally. The only reason I originally bought alpha mags is because I couldn't find any AIs when I wanted them.
