I have an AT-X with at least 1,000 rounds thru it. I played with the one AT-XC that was in stock at Euro Optic recently, I was actually very surprised to find very little perceivable difference in bolt lift between mine and the AT-XC I handled.I'm still waiting to see some direct first-hand reports on the XC bolt lift.
Most people at SHOT didn't realize that the required safety rules of a deactivated rifle meant that AI had to remove the firing pin assembly, and by doing so there's no longer any resistance on opening and closing. The demo rifle at SHOT basically couldn't demo the lightened bolt lift.
I've talked with one other AT-X owner who handled the XCs at MHSA last month, and said he didn't notice much difference. Would be nice to get some empirical numbers describing resistance in pounds.
It's a very nice rifle, but I didn't feel much difference, even with the safety in "fire" position.
Just my experience with a sample size of 1 of each.
