Correct all the way through! The few quarter ribs I've used have been sturdier than what one hears. While I'm generally content with the quarter rib, if I re barreled, it would go. Especially if I was placing a big scope like the ATACR, using an intense cartridge, and then adding brake.
Last time I spoke with Mike he, was using a smaller scope also. I see more issues with the Ruger style rings themselves than the rib.
My current project started with a hunt for an in-expensive donor. Part of the process was evaluating what if anything can be done with the basic system before trashing all but the action, and finding out maybe it was more than adequate without a bigger investment.
So yes if I pulled a barrel the quarter rib would not go back. If I was hoping to use it basically stock the 1V would be preferred. A .300 magnum, stainless, laminated stock, 1V, (if such a variation is available) would be the place to start. For me any way.
Thanks
