User Manual and accessories help BLP M12

[Magnum2230]

Does anyone on here happen to have the correct User Manual, preferably in a PDF format, or even a scanned version, for the SDS import Armelegant BLP M12 bullpup shotgun, and information regarding which choke tubes will work in it?
I've tried the manufacturer site and other forums for help with this to no avail. The only user manual they have is for the wrong model, which has different disassembly instructions than mine requires and zero mention of the choke tubes.

🤣🤣🤣 Yep... I mean it works fine, but if it didn't, there's not once the manufacturer has replied to or otherwise responded to my inquiries. I just need a user manual for this model, and find out exactly what brand chokes will work in it.
Meanwhile, a buddy of mine has ordered some Benelli standard choke tubes that I can try one to see if it fits. It's made like them, but who knows??? 😆 apparently, nobody knows yet... lol nor does anyone have a scanned user manual 🤷 lol
