I was reading up on 922r compliance and from what I understand, If a firearm is not intended for "sporting Purposes" and is not made in the U.S.A. It must be 922r compliant. Since Mosin Nagant rifles have a bayonet lug would this mean that Mosin Nagants are subject to 922r if they are not C&R Eligible? for example, I have a mosin nagant and If I were to replace the stock with a sythetic one the Rifle would now no longer be considered a c&r firearm and doesnt meet 922r requirments.
Thanks in advance!
