Curios is anyone has them to compare, are there width differences? I know the oal in the Dasher/BR is longer.

Reason I'm curious, having a 6arc barrel spun for my Origin.. I'm extending the freebore a fair bit. I already have a few 10rd aics mdt dasher mags. If I can just close the feed lips, will 6arc run though them? I saw first gen polymer mdt aics 6arc mags held long oal, now they are short. Same with the 223 mags. I have no clue for the change, force guys to buy the 2x more expensive mag?
