Tuning Anyone use Audrius internal regulators from Lithuania/eBay?

I got one about 7 years ago for the Hatsan BT65, .25 that I owned at the time. Went in the air tube. I was very impressed with the quality & function for the $62 it cost me. It improved the accuracy & shot count of that gun (& that's saying a lot). Hopefully his "build ethic" hasn't changed. At that time quite a few people were buying them & having good luck. On the other hand, I installed a Huma reg in my FX Boss last year & just can't say enough about how much better my already GREAT gun has gotten. Mine only cost $88 but knowing what I know now I'd have paid $120 for the results I've gotten. Something to think about.

I was using those for many years, they work quite well.
If an issue exists, it would be IMO the seat type being a hollow needle to a soft seat. It works fine until it wears too much. Only been marginally successful in servicing the seat once it no longer seals correctly.

Thank you @Gerry52 and @Motorhead! My problem is that they don't have any pressure reference on the adjustment screw like HUMA has. So how would I know how much to turn it to get the output pressure I need? This seems to become more of guess work. @Motorhead did you buy these regs recently from this 2014_rusy guy on eBay? Or is there a better more reliable source to order it?

My use of them goes back 8+ years now as I've used HuMa in more recent years.
early on the dayz of marauders, they were nearly the only readily accessible reg and sold domestically threw AIR GUN EXPORTER for many years !!

They're all pre-set for the indicated pressure for whatever gun it's going into (he made them for many different makes/models of airgun). If it's for a Mrod it'll be set at the proper bar. If YOU want to adjust it differently email him & see if he can mark different pressure settings (if it's the original mfg/seller). It couldn't hurt. If it's a second party seller you're probably SOL.
