I agree with bighead. What you choose as your preferred magazine is, just that, your choice. Me, I use TAPCO Gen II PMAG in my AR, but in the Corps we had the USGI mags. Have not had a problem with my PMAGs yet, but am sure one will pop up eventually. The USGI we used in the Corps would usually give you a little hick-up, but then again they went through a lot more rounds than my PMAGs are currently going through. Every mag has its positives and negatives. Just try them out and see what you like, what feels good to you, what makes your little killer inside smile and say, "That makes me want to go shoot something." As for all the bickering over I like this one and you like that one, so you must me wrong BS, it's a forum. That is what they are used for to settle differing opinions in whatever manner you want to, so bicker on brothers.
Some people spend an entire lifetime wondering if they made a difference in the world. But, the Marines don't have that problem.
