I have a 1.5x6x32 Simmons Whitetail Expedition scope that I want to put on my Remington 760. I currently have a Redfield 3x9x40 mounted on it with the see-thru mounts. I want to put a base and rings on so that I can have the scope mounted lower on the gun. Not wanting to spend much, but what mount and rings should I get? Also where can I find them? Thanks, Scott Woody
