Ah ha. My fn49 doesn't have a cross bolt for the receiver to rest on. It took me a while to figure out where the recoil bearing surface is. It is unconventional. You may want to look into that too.I have a piece of black walnut and would like to make a stock for my FN49-8mm rifle. I am ready to start ruffing out the barrel channel !! I would appreciate any advise with this task. Thank you Bob Barton
