I doubt it but I'd contact Vince Baldoff in Anchorage.
Probably have to send to Briley Choke tubes or some such.
I do not believe Vince does any choke tube installing. He used to have another (now dead) local "smith" do them.
I have had a large number of them done by several different smiths. Mike Orlen did a bunch but the last go around was horrible.
