That's correct; in order to use the backup sights or red dot you have to rotate the rifle. And rotating the rifle 45 degrees is far better than lifting your head up to find a sight that's on top of your optic. Basically, a 45 degree offset sight is the fastest and most efficient way to have both a close-range and a magnified sight at the same time.
