Now your talking!
A red dot does cover a lot of target but to tell the truth I don't do any better with a scope.
Keep the brightness as low as you can and still see it good.
Use a target that the dot can be centered in.
Sometimes a 3D target works best, like a pop can which is real good at 100 yards. Set the bottom of the dot on the top of the can.
Keep us informed how your dot holds up, also the mount.
