Suggestions for autoloader/red dot combination

[Charlie]

I have a friend who is looking to put a red dot on a shotgun for turkey hunting. He shoots mainly over/under doubles that should not be altered and should get a new shotgun, preferably an autoloader, on which to mount a red dot. Are there any autoloaders that come with provisions for a mount that would accommodate a red dot? What should he get in terms of shotgun and red dot to have a decent combination?

Most newer shotguns have rails on top that allow easy mounting of an optic. If money is no object a new Browning or Benelli , but for more budget minded options Stoeger is hard to beat. I have a semi auto that I have shot multi gun. Matches for the last 3 years that has held up well. Stoeger is same operating system as a Benelli and both companies are owned by the same parent company.
Stoeger M3000 or M3500 3.5” shells with a Holosun dot is a good option
