+1 with CBASS. I wouldn't mess with it either. If you are dead set on the Max-1, go buy a good magazine and have it hydro dipped to match. Or...when I bought my R-15 I got two of the Remington "5 round" mags with it. They both hold ten rounds though. Not sure what the deal is as they are advertised as "five round" mags. They are spendy, but if you don't like it, take it back.
