I bought this rifle from a friend of a friend and have never shot it. The original owner said he had 46 rounds through it since new. I did recrown it, install the muzzle brake, tune the trigger, and install the bolt knob. 950.00 shipped.
The existing knob is turned down and threaded 5/16x24 and then the aluminum one is screwed on. There are several different styles available if you don't like the one on it.
