A red dot "scope" is not really suited for your .30-06 .That would be like putting mud tires on a Corvette.Most red dots offer no magnification and are intended for fast close range target acquisition.A red dot would be ideal on your 870 or 10/22.Check out the Bushnell Trophy red dots.Multiple reticles (small dot,large dot.crosshair,or dot in circle) and 11 brightness settings.Less than $ 100.00 ,I have a couple and like them.
