I've seen them, used them. A laser dot sight isn't generally
referred
to as an optical sight. They have pluses & minuses but I don't think
one would be a bad thing to have on a gun used at 'point & shoot'
ranges, personally.

LOL..................... Dude............. Nobody is talking laser dot
sights. A red dot sight or a holigraphic sight are not laser sights
and are most certainly considered optics. Do you even know what a red
dot sight is? Once again you look like you are out of your area of
knowledge.
