Thank you for attempting to help. The stock can be cut up to an M24 but what is cut is specific to the order placed at Manners. This stock is currently cut to a Bartlein #13. It is not hard to cut out for thicker barrels at all though. Plenty of folks do it with dowel rods and sandpaper. Or you can send it back to Manners and they'll do it in weeks rather than wait 10+ mo for a new stock.
