Yep, it’s intended for the local market in Belize, he told me.
But pretty cool how he can craft guns from almost scratch. Also, the very high handle is nice. Not the most maximized “band length” - same idea I guess as in the One Air/Airbalete - but still very cool

I also had some spare sliders and tail ends made by him a few weeks back but let’s see how long they will take to get to indonesia;-)

Interesting design, but maybe not much of a floater after the shot with all that solid construction in the rear end of the gun, even though it uses a lot of plastic components. Should be easy to pull the trigger transmission pin out after depressurizing the gun if you have to take it apart.
You need to see the platoon mechanism itself in order to judge the feasibility of such a design for transferring force from the trigger! End handles have the ability to trigger directly on the stem of the pressure seal without unnecessary leverage!
I expect that this UBL gun uses the "Italian rocker" for its sear lever which is a stable remote trigger operated single-piece trigger flattened out like a "see-saw".

In the Omer/Sporasub guns the handle hanging off the rear end of the gun operates an unstable sear lever via a horizontally disposed sliding pin, hence its piston has an angled face mushroom tail.

Not! I contacted Dima on Face Book! Standard lever - a whisper for Italians!

The diagram refers to the second sentence, not the first. I have now separated the sentences with a space.
