I have wondered about reducing glare from the sun being behind a scout scope by mounting a tubular lens hood on the rear, not the front, of the scope. It would require a bit of improvisation but should reduce the angles at which the sun behind you causes troublesome glare and reflections.
With the conventionally mounted scope, your head (and hat, if worn) act as a sun shield of sorts to keep sun glare out of the back of the scope. Adding a lens hood to the rear of the scout scope should accomplish much the same thing.
I have not tried this because I currently lack a scout rifle. A light sporter with a low power scope mounted aft seems quite serviceable.
Something I'm fooling around with is a red dot sight, mounted conventionally atop the receiver, but placed far enough forward that it cannot possibly hit me in the eye. This is a good setup, for when the dot sight is close to the eye it gives its largest field, but there is no critical eye relief, so you don't need to endanger your eyebrow. Come to that, I have managed to use conventional telescopic sights without hitting myself in the eyebrow with them, but I am told it happens sometimes--particularly when in a hurry.
