RE: Open Sights look cool
There's a reason that the screws that hold the scope rings to the base have a coin slot in them instead of a screwdriver slot, because most of us don't carry screwdrivers in the field. Something as simple as losing your grip while lowering your rifle out of a treestand can take out a scope. Pull a quarter out of your pocket and take off the scope and you're still in the game until you get back and fix the problem. Hopefully they'll never be needed but considering how much money we spend on every other aspect of hunting it just makes sense to me to have them on the gun.
