Thanks to all that pointed out that closing the bolt make them feed. Guess I hadn't considered that.
Thought I was fairly clear in my post by saying I have had people say they can't get them to feed due to the short case and sharp shoulder angle.
I have a .223 AI but it uses the AI mags. I was wanting to do one with a BDL set up.
I have had two different gunsmiths tell me they have never been satisfied with how they fed. Both of these smiths are well known here at 24hr.
I thought I read once about a mag mod for the 223 AI with an internal mag design.
Guess I was mistaken
