Guys, when I was at the gunshow last weekend, a few of the venders were selling silencers for several different models of ak except mine:/. All of the told me that in NC its legal to buy and own a suppressor as long as i have the sherrif dept.s written approval, yet I see nothing mention anywhere in state law about this. Can someone possibly fill me in on some truths and if it is legal where to find some quality suppressors. Thanx
