BIZON: The Pistol-Caliber AK SMG
Building a Bizon in 9x19mm.
Added new pics I've found on some Russian sites:
Bizon-2 pics from the Factory website:
Put up some pics of the real Bizon SMG to show the modifications that are needed to modify an AK into a blowback/recoil operated configuration for pistol calibers... interesting to note that the internals of the Uzi are similar. I suspect most blowback/recoil operation designs are the same:
These pics are all credit of Vlad:
I noticed 3 things of interest... the gun is DIRTY and needs to be cleaned. Next, the barrel pin appears to be the full-length AKM style as used on milled receivers (and Chinese rifles). Lastly, the ejector is larger than I expected it would be.
This one may be a fake, can't verify. If real, it appears to confirm what I have read that the Bizon can accept standard mags. Will try to find more info on this one. Update, looking over the RussianArms.info site, saw several Krink & Bizon builds that appeared to be custom or limited-production models. So it looks like this is a real model but possibly a customized version, probably for OMON or Spetznatz use:
Good-quality pics from russianarms.info:
Update - a new 9x19mm model called the "Vitiaz":
Factory presentation pics. Note the optional Picatinny rail on this model - from the Russian factory!

Some pics from Rhino (pretty sure) - concept pics visualizing the alterations to the bolt and feed area. He's working on a .45 ACP mod using Thompson mags.
The Master SMG (9mm)
Exploded view of the US-built Calico helical drum magazine. Pretty sure the patent has already expired. I'm not using this design, I'm using a worm-drive mechanism similar to that found on a grain feeder or meat grinder.
