No,it's not anorexic. My new 223 AI shoots great but I'm having a heck of a time to get it to feed from the magazine. It was a standard 223 before I rebarrelled it and it feeds regular 223 loads just like it should. The rounds hang up on the breech face about half way in and I have to mess with the bolt or start it the rest of the way by hand.This is the first AI I've had problems with. Any suggestions?
