PMAGs are a looks thing.
Unless you are using 10+ year old usgi mags replacing the stock followers with the magpul ones serves the same purpose.
Personally I like and on occasion use my pmags for military purposes but have never had a single misfeed or problem with magpul followers on usgi mags and have easily fired 9K rounds through them.
Sure, I've been called a xenophobe, but the truth is, I'm not. I honestly just feel that America is the best country and the other countries aren't as good. That used to be called patriotism.
