Airmaks Krait barrel

Can anyone tell me what barrel krait uses? CZ berrel ? square or circular rifling ? Who owns the krait please give me some pictures of the barrel's rifling. 1 or 2 ?

Mine is .177 😁
You made me do it! 🫵 🤣 i just love you man! great work on YT.
I bought Krait L and i'm still messing around with it. found few things and worked on them and need some help to solve some problems tbh! I love the gun and i think it ĥas what it takes to be one of the best.
1st. issue was the barrel, had a ridge 'hump' just after the air ports 'breach side' i polished it with Dremel and got them soften up and smooth transession now.
2nd. had few tight spots along the barrel and i polished it and now just 2 spots left and i'm affraid to polish it more tbh!
3rd. if i increase the reg pressure over 150Bar, i would have valve lock and the hammer can't open it!

any tweaking ideas? i would really appreciate it! thanks.

P.S. mine is 0.22 cal FAC
