Building a Bizon in 9x19mm.

Added new pics I've found on some Russian sites:

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.

The important things from these pics are the views of the bolt and carrier, to see the configuration of the bolt without the lugs.

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:

Additional Photos -

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.

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.
