Yes, that's an actual working violin made to look like an M-16. The person posting the picture said, "This is a violin designed by artist Wei Lieh Lee to look like a machine gun. Yeah, a Stradivarius is pretty nice, but last I checked a Stradivarius never gave Arnold Schwarzenegger a boner." but I call him an idiot because that's not made to look like a
machine gun.
ANYWAY, I'd sure like to have one of those...
