There is one useful attribute of a red dot scope.
It's pretty easy to find iron sights even when the gun isn't pointed correctly at the target.
No so with a dot scope.
Get sloppy with the gun and the dot can disappear out of view completely.
No telling where it went, up or down or left or right or somewhere else.
Using one really helps get your form correct or you can't even find the danged thing.
Lock the doors, they're coming in the windows.
