It's not really a DIY question, but can anyone recommend a place (or person) that can tap a shotgun barrel for threaded chokes. I have an old Wards Westernfield semi auto that has a modified choke barrel. My neighbor suggested that I see if I can get it tapped so that I can put in different chokes. I know some may say it's not worth it on an old inexpensive gun, but it's still cheaper than buying a new gun with multiple chokes. My neighbor gave me the name of guy that has worked on his shotguns, but when I called him he said he does everything but what I am looking for. I am in Macomb county and work in Troy so if there is anyone in that vicinity, that would be preferred. Thanks.
