As long as the scope doesn't touch the rear sight I'd suggest you just ignore the fact you see the sights in the bottom of your FOV. I've had that happen many times with scopes with wide FOVs and it's not an issue really unless you make it one. You can always remove the front sight which is usually the one visible in such cases but it hurts nothing to leave it in place. I like my scopes mounted as low as possible so long as the scope is touching nothing but the rings.
