Hatsan bullboss regulator

[rabbitguy]

Does anyone know if this is the correct part. I purchased this from wingsupply , it looks different than what they have pictured as a bullboss regulator.
The end is threaded but this regulator has no orings like the one that pictured on their sight.

I am trying to return it but They are giving me the hardest time.
This one came with lock tight on the threads and wear marks near the inlet side. It’s definitely a used item.

It has threads like an H-class Hatsan regulator but the missing body o-ring and seam are concerning. How you are supposed to adjust the one you show I don't know.

On the actual Hatsan regs you simply pull apart the two halves and turn the adjustment nut.

Maybe Hatsan changed the design but the one you received doesn't resemble the images on the Hatsan website. I have a couple BT65 and one non-H AT44 regs which look exactly like the images on their website.

The plenum comes off to adjust.So much misinformation here. There are very clear instructions from hatsan on how to install and adjust this regulator. A little research will go a long ways here. I have hatsans and use 3 of these regs and they work fine. Mine are on bt65s.

Apparently it's the correct part, they are just using the wrong image in their listing. Maybe they should just change it to match, but that would be to hard right.

I did find the picture of this regulator listed as a bullboss reg on a 2021 field supply ad. But now they changed the picture to the regulator with orings on the plenum, go figure.

I might try installing it this weekend, see how it goes.

Hatsan may have changed the plenum design but they apparently haven't changed their documentation photos. All my Hatsan regs look just like the ones in their installation/adjustment docs.

edit: Wing Supply and Field Supply are essentially the same company. They mirror the same stock (and errors). They also flip-flop sales and price changes. I always check both because one will have the lower price for that week.

This post seems to explain your regulator.

Plenum should unthread from regulator valve body? I'd install it and try to get it working.

Was it sold as "refurbished" for a lower price?
NOT Wing Supply (yet) but several times with Field Supply I have purchased refurbished air guns that arrived in fair to almost non-functional condition. I accepted those items because the price was appropriately low AND I enjoy the challenge of repairing other folks incompetent efforts. In my experience "refurbished" from some sellers can mean anything from "factory refurbished to like new condition" to "customer return that looks OK to us but may not work so good". FWIW all of the "sad" air rifles I received turned into nice shooters with a little effort and a couple extra $ in parts. IMO well worth the effort and cost for the discount received.

Good Luck!

Nope not listed as refurbished, but they did send me pictures of the 3 other regulators in stock. They all looked like the one I had. He said that’s tooling marks and grease from the factory. Not sure.

I did get it installed today but haven’t tried it yet, maybe tomorrow.

Thank you, for the link. I tried and tried but couldn’t find anything on it.
Wow, Thanks 👍
