I'd say go with a middle of the road red dot sight. You won't really need any kind of magnification with a shotgun.

I need it for this gun,

For turkey hunting and BSA won't cut it, can't handle the recoil. I'm stuck between the Nikon 1,5-4,5x 20.the I.O.R 4x24 and the Aimpoint 9000. Does anyone have a 3 sided coin?????

Of those three choices, I'd recommend Nikon. I've got Nikon optics on a couple of my rifles, and I've yet to be disappointed with them. The lenses are amazing how clear they are.
