I wanted to know what options are available for rebarreling one. Plan to retain the factory recoil lug/ notch as rifle is currently in a xlr chassis. I seem to find different info on what the front of the action looks like, some say the barrel shoulder is recessed some imply it is flat like savage/ Remington. Which is it? If it is recessed can that be milled down and a traditional shouldered barrel of any od be used. Talked to my smith, Geoff Corn, he has worked on a couple but that was 6-7yrs ago.
