That really does look similar to an FX! Unfortunately, I don't know what the sizing is
Hatsan probably some metric threading and FX standard threaded.
I will try and check mine later tonight, but most likely, it will be tomorrow. Can you also measure the length of the male threaded part? You'll need to know that too.
The lengths are close, but I got 11.5 on the OD, so it's a no go However, it looks like you can screw that valve assembly out of the factory bottle. If that factory bottle is a standard threading, you could just move the valve to another bottle, right?
You aren't the only one waiting (impatiently) to learn more about both hatsan bottles and regulators.I like my factor, but I do believe the lack of a regulator is working against me, so I plan on investing in a regulator to make the overall shoot more stable.I've searched and while there are a couple of alternatives available, this seems to be the best right now:https://www.altaros.cz/domu/149-hatsan-factor-airgun-regulator.htmlUnfortunately... while I seem able to find replacement bottles (brand doesn't seem necessary since most bottles sans regulator appears to fit!, the attached valve or a working equivalent is nigh impossible to find and don't get me started on trying to find a hatsan branded regulator, though there are viable alternatives (see above link for example).They claim all components are readily available, but if thats so, WHERE!?

But since it's unregulated to start with (and the valve/spring/hammer spring expects to 250bar) I expect to get it to work properly you need to change out all springs to softersprings if you want to run it at ~140 bar. I get the feeling I'm just wasting air and have no precision.It now stands in a closet. I bought a FX Maverick, more power to tune it where you like, and I got the double shot count on the smaller 300cc bottle (Compact converted to sniper). Very efficient.
