There is a pre-ban 10/22 sitting at the local gun shop with all the standard stock and hardware. What can be done to such a weapon cosmetically and still be legal. For instance, can I drop it into a folding stock and put a flash supressor on it? Or can I do only one or the other. If you can't do these things, then why are the parts sold in the first place. If I can only do one and not the other then why buy a used pre-ban when I can just get a new one and put a flash suppressor on it? Could I at least use a stock with a fixed butt, but still have the pistol grip and flash hider, like the one they show in the Cabela's catalog? Thanks!
