Got to reading a little bit more about SKS rifles and imported rifles and shotguns in general. What I found was that the gun needs to be 922 R compliant. Since I did not modify the rifle in any way shape or form, I am compliant with 922 R. So much for putting on a new Tapco black stock on it. If someone was to change 1 thing, add a muzzle brake, add a scope, change the stock it now becomes non compliant with 922 R. Google 922 R for an explanation because I might get it wrong trying to explain it.
If you modify an imported rifle or shotgun it can not have more than 10 imported parts on the gun. to include things like the trigger, trigger guard, magazine, piston rods, gas cylinders, and a bunch of other stuff. It's a brilliant rule, no one has been found guilty of it as far as I can tell by reading about it. But I'm sure some yo yo anti-gunner is just waiting for an opportunity to nail someone. I think it might be about buying imported gun parts and building your own gun illegally.
So if you own an imported rifle or shotgun, don't modify it. If you do modify it make sure you have no more than 10 imported parts on it. Crazy stuff out there but I'm glad I stumbled across this. Boy, would I be upset if I changed out the stock and got nailed at the range for a non 922 R compliant gun. I don't want to be the first I would make a terrible poster boy.
