Product Description
This tool is used to help with the alignment of SKS muzzle threading. It has the marked thread on the outside.
Essentially the situation is you want to put some muzzle threads on your SKS in a diy type situation.
You can usually run a M14x1 or 9/16-18 die directly on the muzzle of the barrel in front of the front sight/ bayonet block
These cheap tools will make sure you have a precise alignment while making those threads.
