ccw for a rifle? is that right? can't be. down here "bubba" rides around with thier rifles on gun racks in the back of thier cars. usually ccw only is for pistols only. check your state laws.

it should be legal for you to display your wasr... but if your worried about some parinoid trooper pulling you over, just keep your magazine out of the rifle, but within arms reach in case you have to use it.
