Is there a product out there such as a 12 gauge tap, to take a cylinder bore and thread it to accept chokes? i.e. I bought a shotgun that was just cylinder bore and I want to be able to screw in different chokes.
Also if it would just be cheaper, is there a place where I can just send my barrel off to and they can tap it for me?
Thanks

Many places like Briley will thread your barrel and supply choke tubes. Unless you have access to the equipment and are an accomplished machinist, it is easier to let someone do it

Brownells sells the tooling, but you will need a lathe to bore out the bbl in any case. If it is a modern shotgun with interchangeable bbls and they sell what you want as a spare bbl option, that would be the cheapest route. By the time you pay someone to do the work and buy a few chokes you are way over what a replcement bbl would normally run.

If one were to get the tooling, get it from Pacific Tool. If you have any questions about them, go ask a benchrest shooter. I have seen Dave's work, its unreal.

what gun do you have? its better to get another barrel if its a 500,870 etc...

Sporting bbls threaded for chokes are affordable and easy to find.

Shorter bbls for defense shotguns, not to much...

I hate to sound like a search nazi, but we just had a thread about this not long ago. Briley's, Mike Orelen (sp?), Carlson's, and Colonial Arms were mentioned, maybe another as well.

Alternate question on the same topic:

After a Barrel is threaded you need to re-blue (or Parkerize, or paint it camo) it because Bluing is a surface finish and you want it on the threads right?

No, you don't have to re-blue it.

Most factory barrels are not, and many choke tubes are not.

You need to keep the barrel & tube threads coated with choke tube or anti-seize grease anyway, or powder & wad fouling will lock them in place tighter then a bulls patootie.
