Have not touched the barrel channel. I did pull it out of the stock just to take a look at that Mickey Mouse recoil lug setup before I fired it. The action screws were loose. I loosely re-assembled, bounced the butt on the floor (with feeling) a couple of times, and then torqued them both to 45in/lb with my Fat Wrench. Figured I’d bust the plastic bottom metal but no. I tell ya these things are something. I’ve got customs I have $1000’s in with custom actions and expensive barrels, hours and hours of my own work standing over a lathe. I can’t do any better. Sort of disgusting, actually. Guess I’m a fan boy now but I do curve my hat bill
