To answer some questions - you can get scope bases for these original Kimber of Oregon rifles. The receiver was drilled and tapped for bases by Kimber when produced. I do have the original one-piece dovetail base that Kimber provided with the rifle and it will go with the gun. With that said - I would not personally use it as it looks more like a cheap rimfire base that uses rimfire clamp on rings and I would not trust it to hold a zero. I can help I.D. rings or bases for the buyer of this rifle. Also as noted a couple of times - this is a 100% factory rifle chambered in 6x45 at Kimber of Oregon factory when built. Zero modifications to the rifle as built by Kimber. Hopefully this helps.

Thanks
