I put an IMUNS on one of my AICS 2.0 chassis, and it won't fit flush. I have a pair of these chassis systems, so I actually installed it on the other one and have the exact same issue.
I'm working it out with Mile High and Badger, but I thought I'd ask if anyone else has had this problem.
That is a very generous offer! I have a rifle with a local gunsmith right now, let me see if he can do it for me when I pick that up, otherwise I will you take you up on it.
