I've never had the occasion to re-bbl one.
The NAA parts diagrams on their website(s) show the frame and bbl as one factory part/assembly. They probably wouldn't sell a bbl separately, many mfg'rs won't anymore.
But sending the gun in for a bbl replacement would seem to be a normal operation,,if they ever respond to your inquiry.
I do notice that Numrich sells some NAA factory bbls for the revolvers.
Just looking at the pics they post of the parts, the bbls look like a simple threaded shank.
About all I can tell from the pics

Is the bore pitted?,,or is it just the outside that got damaged?
These are stainless steel I presume,,so the outside finish can be fixed up w/o much effort.
A pitted bore probably doesn't show much difference in coffee table distance accuracy than a clean one. But I realize most people like to have a nice bore on all the firearms they own.
