Red Dot for shotgun???

[mikeinla]

I have two Remington Versa Max 12 gauge shotguns. I was thinking about adding a red dot sight to one of them. I also have a few red dots sights laying around. Would either of these sights hold up to a 12 gauge??

I've used the Doc II+ on my Beretta A400 with 3" turkey loads, you're good to go with it IMO. My 14 y/o son shoots a VersaMax 12ga. for duck hunting, they manage the recoil very well with 3" #3 duck loads, if you're shooting 2-3/4" shells you probably don't have much to worry about with any of the optics on your list.
