Leupold V-6 1-6 power. 30mm tube. 1x you can easily see with both eyes open. You'll never use your open sights unless you just want to. 1.5x and above both eyes open may or may not work. 2x and above forget it. The 6x is plenty for anything longer range in a 375. Next choice any other good 1-6x scope (not 1-4x.)
