I'll cast a vote for the Hiviz-Triviz Turkey/deer combo sights. Adjustable for windage and elevation, and the front sight is circular to surround the entire target so that the field of vision is whole, if that makes sense. Much different than throwing the bead on the turkey and not seeing much, if any of him, at 40 yards.

That said, I have the Truglo pro gobble dot on the Mossberg and that is not bad either.
