I have a Redfield one piece scope base and mounts for a short action Remington 700, 1 scope tube. It is medium/low and measures 12mm on the front of the base from the receiver to the bottom of the scope ring. It should be fine with up to 45mm scope.

Ideally I want to swap it for a 2 piece base mounting set up for a Remington 700/Howa.

Or sale for 20 plus post and packaging.
