There are silver solders that work with stainless as well, including some of the easy pastes. The easy pastes tend to be some of the lower temp mixes. At this point, I'm going to advise anyone considering heating their barrel that hot to consult with a barrel smith on the proper way to do it as well as the proper cooling rate to prevent causing a martensitic transformation.

Unless the enforcement people insist upon a gunsmith certification of what it was soldered with, you could get away with an Ag/Sn soft solder. though it's referred to as soft solder, that stuff can get pretty hard without incurring such high temperatures and for all outward appearance, will be permanently mounted. If you hit all the threaded area, it'll probably be stronger than a pinned and welded hole mount in the long run.
