I know that JG sales used to offer these, along with at least one other retailer. Having spoken to one of the guys at JG, I understand that the manufacturer closed-up shop several years ago. Still, if any of you have one of these and could be enticed to part with it, I would really like to have it. The complete kit would be preferable, but I would settle for just the barrel, if that is all you have. Contact me, and we'll haggle.
