Any advantage to using USGI over PMAG?
So I have about 10 of each, and I've been trying to figure out if there is any advantage to using metal magazines over Magpul PMAGs. I'm debating selling off my USGIs and getting more PMAGs. My Colt, Noveske, and BCM lowers drop free on all of them.....so there are no fit problems.
I remember that Alaskapopo said that he was getting cracked feed lips on some PMAGs in subzero winters in Alaska and that he prefer USGI for that reason. However, I haven't heard anything further on this topic.
So, other than that I can't find a reason why not to only use PMAGs.
