I'd like to see some steel mags for the s-12. I've been an ar guy for years and have over 80 mags, 50 or so that are c products. IMO They make a great ar mag, never had a problem with one. So if he does his homework I'd be happy to buy some steel mags, but I have no complaints about my surefire 12 rounders(I've got 5). They have worked perfect for me, but everyone seems to have a different experience no matter what. Just my 2 cents I'd also like to say thanks to everyone on this forum, it's full of great info.
