ZB47: A Truly Weird Czech SMG

[carbonbased]

Ian has a neat vid on a weird gun, the ZB47. Obviously the P90 took inspiration from this thing.

I liked the bit where they designed a modified 9mm case to accommodate their poor magazine design then tried to come up with a list of "attributes" of a proprietary cartridge.

Almost as though they were writing for Gun Digest, Recoil, or any other gun rag from the past 100 years…

It might be interesting to see a revival of the design but flip the magazine and rotor 180 degrees, do like the Kel-Tec P50 and have the magazine under the barrel, and you wouldn't need as long an action arm to rotate the mechanism either.

would make for a very compact bullpup style PCC if it was done right, and rotary mechanisms are generally very reliable.

make it a quad-stack using a single-plate follower and you might be able to get over 100rds in an extremely compact form factor, and having four columns of 25-30 would reduce the problem of binding from case taper

I watched that and would love to have one. Outside of the slow mag changes, it seems like a well working smg. Something like 1,200 rounds a minute cyclic rate.
