PMAGS are over rated... However, SKD tactical just became one of my favorites..
In a normal market, they are a hell of a magazine for $12-$14. Given their reliability, price, and the fact there are a glut of them out there, I am perfectly happy running them. And that's not to say I wouldn't take a USGI mag or similar any day of the week, but given the choice, I am happy with PMAGs.
