To determine if an SKS barrel is pinned, first visually inspect the front sight block and the area where the barrel meets the receiver. Look for a small pin or stake that secures the barrel in place; it is often located at the rear of the front sight block. Additionally, you can check for any signs of welding or soldering, which might indicate the barrel is not easily removable. If you have a gunsmithing tool set, you can also attempt to loosen the barrel nut to see if it is secured by a pin.
The rear sight must move in the direction you want the point of impact to move. The front sight can be moved in the opposite direction.
