That is so awesome..
Don't have a MAC.. but this will make me want one.
I remember MGI suppose to make one for the AR platform but never saw it happen. This would be amazing.
Look forward to your testing. I'm assuming you'll post it on uzitalk forum? I'd very much like to follow the progress.
My American 180 is a tight fit. I can see it fail if not fully seated. One of my barrels barely fitted so I had to file it down a bit. (Didn't fit because who ever worked on it has it slip on a lathe or mill which dented the part that slides into the receiver.
