What gunsmith threads 28 ga barrels for choke tubes?

[deadbuck]

Have a NEF Handi gun with 2 barrels, a .410 and a 28 gauge. Who threads these with a thread pattern other than Tru Choke thread pattern? I know Rose Action will do the .410 in Winchoke but they dont do any 28 gauge.

I have used this company for custom work. They made me new firing pins for an old pederson O/U when no one else would touch it. https://www.ahlmans.com/gunsmithing.html

Briley

Called Briley and they said they "May" be able to do a factory thread pattern but I would have to send barrel in for them to examine. I asked what internal and external diameter it needs as my gunsmith can measure it and determine if it is a likely candidate before the 2 way shipping hassle and charges but they insisted I send it in. Not interested in their thin wall thread pattern as choke options plummet then.
