Am I also wrong on the mods making it no longer C&R ? If it does , does he then have to take it out of his bound book as a disposition to himself?
I wasn't aware that the muzzle attachment was the reason more parts have to be changed to make a Yugo SKS compliant.
Although my information on the OP's SKS was flawed, I think it's important for people to realize there may be legal issues with "modernizing" some C&R firearms.
