I have a .300 RUM barrel and bolt ( w/o ejector and spring) for sale. They came off of my Remington 700 Police and that had easily less than 200 rounds thru the gun. The barrel is in great shape and I've shot less than .5" groups with it. I'm asking $190 for the bolt and barrel plus shipping. I had 2 so the Police was made into another 6.5x285 for hunting use this time.
