Long before Political Correctness came into vogue.

Lotsa fun but require hours of ammo reloading.

I want one of those

I can't imagine the PITA required to get one though, if they're even legal for a private civilian.

They're antique weapons and anyone can own one. If it doesn't look like or carry the stigma of "assault rifle" the airheads could care less.

That basic 1860s design is the basis for the incredibly high speed Gatlings used in the A-10 WartHog, C-130 gunship, and various attack helicopter weapons today.

The A-10 is built around this 20mm or 30mm Gatling gun - https://www.youtube.com/watch?v=N60WtGC4ejo

Here's a part of my black powder revolver collection - no permits or checks required. .36 and .44 Italian (Uberti) replicas and Colt reproductions from 1851 - 1864 models. Of course, they aren't exactly concealed carry or rapid firing semi-autos, either. Cap and ball.
