Nice to see! You sure dont hear about the Vulcan's much. My Vulcan tactical has been a pellet stacker with out any problems. The truth of the matter is, I really dont hear of any people with problems. With Ernst Rowe's video's it make's the easy to get information on the Vulcan's. I personally have only adjusted the hammer spring and removed the shroud to cleaned the barrel. But super easy. For what ever reason the Vulcan's have slipped thru a crack and have gone unnoticed.
