I just got my hands on an aluminum 10/30 'mag with the tool installed, just to give it a try and I must say that I like it a lot. There's nothing like slapping a metal 'mag into place; the look and feel are great and it functions fine so far. I will probably buy more of these things and retrofit my existing standard 'mags with your ultimate bullet button tool. Additionally, the temptation to install the ambidextrous 'mag release is VERY tempting with this bullet button tool installed...
Crashing gun control rallies is fun, but absolutely necessary, anywhere and everywhere they take place so that the truth about guns and violence can be heard:http://mykranili.tumblr.com/
