Made by Vulcan?

Run away, far FAR away.
Vulcan has also done business as Hesse and Blackthorne, and periodically has to change their name to avoid their poor products. They have an astonishingly bad reputation, and the one Vulcan I ever held was the worst piece of junk I've ever laid eyes on. Things like the safety selector, rather than moving smartly and precisely, was mushy and would not stay in a given spot. The feel of the rest of the thing did not impress me... the Century AR I've seen was, by comparison, a model of quality.
If you buy a Vulcan rifle, it might work, it might not, but it surely won't last. I'm not saying this telling you to buy a high dollar rifle, I'm saying buy ANYTHING else. I wouldn't take one if it was given to me. Complete and utter junk.
