In my spare time I, build single shot 22 and single 25acp pistols. I have a source for 22 barrels (ebay) but, I would like find somebody local. Maybe a gunshop that has broken guns, or guns not worth repairing. Usually, I either buy 22 rifle barrels, cut them, rechamber, and crown if necessary. Sometimes, I buy barrel liners. Please, do your research, before you start accusing anyone of illegal activity.
