The Leupold 6 X 42 or 6 x36 Long range duplex is light and seems to work and hold zero.
Was going to suggest the same.....
+2 on the Leupold 6x36. If you want a variable, then the Leupold 2.5x8x36 which I currently have on my Go-To rifle...
Either scope mounted in a set of 16Bore / SAS modified extra low Talley rings. If you can't find a set of the modified rings when you get the rifle, ping me. I may still have a set collecting dust... Somewhere...
