Nothing like a Nightmare, although the design was ripped off by Aldo in Canada who knocked out that piece of crap over and over again. The internals are different. The Guys in Ohio at PUMA Enterprises were dedicated hard working and committed. The C&C machining on the gun barrel is comparable to current machining and since this one is one of the very first maybe first 1-5 ever made, the grip assembly is cast aluminum and not quite that finished smooth. The grip covers are fiberglass. I had 4 PUMA'S 3 short barrels and the long barrel I traded in 88' for a short barrel. I also have the original Schematic and Manual that break down every part. Actually haven't even seen another long barrel to date.
