Found an example 20 gauge with a full choke barrel. Priced right, but with a full choke it might not work so well for dove. Is there a modern affordable barrel with screw-in chokes for it? I can see getting a "great deal" but then having to put a lot of money into it...not a good thing...

If you got enough meat at the end of the barrel there are some gunsmiths that can install screw in chokes for ya
