If you have a Leupold on it keep it on. You have a scope that manages light better than any red dot around. Red dots are originally designed for fast target aquisition. If you use a no-magnification red dot with both eyes open it will work in darker situations. I've often sat in a blind with tall trees surounding a small patch of grass and it got so dark I lost half an hour of legal shooting time. I've found a decent low power scope with good light management to be far superior. The scope of my choice is a VariX 3. The second choice is my Nikon 1.5X6X42 Monarch Gold with a 30mm tube. The third choice is a 1.5X6X36 B&L Elite. I have had the Bushnell Halo on but wasn't overly please but I am going to try it again. The Halo is far better for light loss than any of the Red Dots. I've owned a Bushnell red dot years ago and the battery leaked and of course turned it to garbage.
