Is there a 5 round AICS pattern .223 mag that will allow seating out at 2.500-ish? I know there are 10rd MDTs but I want minimal protrusion from the underside of the rifle. Is filing out the nose of an Accurate mag the best option? I really wish MDT would make a 3rd flush fit like they do for the larger rounds, but they tell me there's no demand, so they have no plans to release one.
