I have a Remington 600 in 243 with a 5 digit serial number. I had actually bought the rifle for the action and trigger to make a long range pistol biuld but have switched directions. Action is in great condition other then the bolt finish being a little dull and needing polished. The barrel and stock looks ok but the plastic rib has a couple of cracks in it. I was looking to get $365 plus shipping to your FFL. I can send you pictures if you are interested just let me know. I am also listing this under parts section as it would be the perfect action for a lightweight or long range pistol biuld.
