I really like the Uragan. Wish I could buy one!
And I really appreciate the
creativity of some mfctr to put more power/ more shots
into a short rig.
▪The Uragan King is doing that with
front twin bottles (there have been a few others on that particular road).
▪The Leshiy 2 got an
add-on airtube in its folding airtube/stock.

As a shooter fascinated by necessity with powerful yet short inconspicuous AG I have been wondering
why we don't have more designs to increase power/shot count of short guns. 
(1) For example, the Uragan Compact is awesome short, love it. But the bottle is really just a short little stub,
an air egg more than a air bottle!

Why not make the bottle diameter larger — for more power/more shots?

(2) Another example: If we go with such slim bottles as the Uragan, it seems like we should be able to
get a second slim bottle or airtube worked into the stock of most bullpups.
The Verminator Extreme (non-bullpup) has done that — but in my eyes the bottle is not slim enough so it looks — in my opinion — ugly (apologies if you own one). The Leshiy
did use a slim tube, and it looks good.
Just my 2c.
