The newest Zbroia have been unveiled at IWA 2019 in Germany (The new and now available KozakFC). The KozakFC (FC for fully compact) can be be thought of as the full bullpup version, while the original Kozak is more like the Tactical/semi-bullpup version (The original Kozak is about 4 inches forward in the stock, as opposed to a true bullpup which starts at the butt plate).
The KozakFC should prove to be very popular, like their Kozak brother.
Below is a video from IWA 2019 in Germany, showing the KozakFC, as well as the other Zbroia rifles.
To be honest, .177 is not very popular. About less than 1% get a .177 caliber in Daystate, FX, Vulcan, Zbroia, so the order will be limited to mostly .22. If you seriously want a .177, I suggest you let us know, and we can always put an extra .177 in the orders. We order monthly or so, but it might take a couple months if it isn't in stock.
