Picked up my new Ranch Rifle with the Magpul 10 shot AR magazine today. The magazine is loose in the magazine well. I have to keep upward pressure on it to get it to feed and it still won't feed reliably. If it does feed the bolt won't close on the round whether it's reloads or factory ammo. Has anyone heard of similar problems with these rifles? From what I've read the AR type magazine was supposed to take care of the trouble some owners were having with the original magazines. Never heard of the chambering problem before.
