Speaking about rails. Did yall know the ATX rail rail doesn't match with the ATX foreend rail. ATX vs High AT rail has the beveled edge. Just a fun observation
It wont work on an AT, I tried and the barrel will touch the top rail. I moved it to my AW and it works fine. For AT you'll need this one

Just popped off my locking plate on my AW and the IMUNS is still super stiff. I think you're good haha. Looking at my diagram and going off my memory, the mount is really secured by the large roll pin that goes through the chassis and mount. (#10)
I use nickel anti seize and use German guten tight specs on my ATX. My friend had an issue with his carbon proof barrel on his AXSR, shooting 3in groups; he bumped up to 55in/lbs and now it shoots awesome
