hey,
any suggestions on a red dot scope that can take the pounding of my mossberg 835. I use it for deer hunting. The recoil that the gun put out when I use slugs. this gun has broke one scope already and i need something more durable. the reason i want a red dot is, because want to make this gun tactical.:bang-bang:

I haven't tried one on a shotgun with slugs yet, but I would look at EOTech.

I-search for tactical shotgun red dot sights, and you will find that Mossberg markets one, as well as the Burris shotgun sight that mounts between the rear of the receiver and tha butt stock. There are lots of brands and models that are supposed to be good for shotguns, I'd start contacting the manufacturers.
I have no personal experience with them, I haven't been tacticool since 1969 at Ft. Benniing.

EoTech, Aimpoint, Leupold, Trijicon will all hold up great on a shotgun.
