I just got 10 PMAGs in the mail today - they are quite nice. It doesn't matter where you push on the follower, it goes straight down. They are sturdy too. I don't know what kind of chemical it would take to dissolve whatever they're made out of, but I think I should probably find out so I can avoid that. Other than that, I think they're perfect. I loaded 8 with .223 TAP 75 for HD - the other two will be for the range. Next month I'll get 10 more in another color for some 5.56....
I liked LaRue's prices best from what I could find - I know you can probably get a better deal shopping around and with a mil/LEO discount, but I paid regular price for mine and have no regrets.
Bragging done for now.
