I doubt the inletting will be the exact same. It always seems everyone has to do at least a tiny amount of inletting somewhere on aftermarket stocks to get any bottom metal to line up correctly. And getting CDI to do it seems to be worth it...you'd only have to ship them the stock (don't see why they'd need the entire rifle). Personally I'd buy the bottom metal of your choice and inlet it by hand. I did my B&C M40 with some cheap files from harbor freight in about an hour while sipping on two beers haha. Turned out quite well actually
