Guys, I have just purchased two 10rd mags for my Argo .308 and the followers are different. One is solid plastic and the other one has a metal splitter on the front part. Both take 10rd and fit my rifle. Though the one with the metal splitter is not loading the first runs very good. I have to forward assist a little. Maybe bc it is crisp new. who knows what is the difference between two types of followers and what is this metal part that splits the follower for. thanks in advance.
