RE: new broken gun question???? What should i do?????
You should bring it back to the dealer who in turn sends it back to the manufacturer. Find out which sporting goods store donated the rifle and give it back to them. They send it back and the new rifle will be delivered to the store/FFL.
Did you fill out your paperwork on the gun yet? In NJ, thats how we have to do it. Civilians cannot mail firearms. Holders of an FFL do that.
