I have the 4-20x50 on my .270 AI and they are awesome optics.

Note: You can see the bedding compound on the flat rear.
I normally use a two piece base set. I am left handed and most all one piece bases are opened up on the right for brass clearance on right hand actions. I also prefer a larger opening for the internal box magazines.
Yours seems like a twin to my 110 30-06 made on 1998, flat rear. My SN start with f408??? How close to that serial is yours?
