Received by M1A with Archangel stock about a week ago. Been shooting Savages up to this point. I installed a Sadlak scope mount and scope, along with a bipod, It was a bear the remove the clip guide. Anyway, although I haven't been to the range yet, my concern is the magazine. It seems that when I install a empty mag, it goes in so far as to hang up the bolt when the bolt is pulled back. Is it the magazine, or is this normal?
