anyone know of an outfit that will do 1 or 2 barrels?

About a year and a half ago I didn’t even know what it was until I found out Kel-Tec has gone away from the chrome lined barrels in favor of the salt bath nitriding for their SU16’s line.  I looked it up and stumbled on this YouTube video. If I understand him correctly sounds like they do small orders but sounds like the more you send in the cheaper it is. I’d sent my SU16-A back for to the factory for a cosmetic repair in last year and they replaced the barrel with a SBN barrel.   FWIW the outside texture of the SBN barrel did seem like it could take more abuse than the original barrel.I recently did a traded the SU16A. Anyway good luck, contact them all they could say is no...
