So I have this falcon and I have a leak at the fill end of the cylinder ( valve part) not the valve but leaking around the fitment of the valve into the cylinder. There are no pinholes for any type of spanner wrench and the brass shoulder of the valve mates flush with the cylinder end leaving apx 3/32 of brass showing at the end of the blued cylinder tube. There is apx 3/8" long 8-9mm threaded nipple that either the fill probe adapter fits to or a 1/8 qc can be used. any ideas how to get it apart to reseal it. Drove me nutz figuring out what was leaking starting at about 400psi . Thanks in advance for your thoughts, Chris
Check the Falcons Owner group on FB. There are a few guys there that can help you.
Whenever someone mentions a maker/model I've never heard of, I go look it up.
Sometimes it's like... ew... you deserve to be punished for buying that...
This one, wow, really nice stock design!
@xmdx13x other than the fact that i have never used facebook ( really do not want to become involved with it) any other places to try.
Airgun BBS or another UK forum.
The FB group has a few guys that make parts and former dealers on it. I can post your question if you want. Probably help if you could send or post a photo of the fill piece.
At this point I know that :
1 there is an o-ring on the valve assembly internal to the air tube- strictly a friction fit as it sits behind the threads on the valve. Wiil need replacement.
2 it does unscrew but has likely been treated with locktite or something similar on the threads ( Heat to break down)
3 will have to make a couple tools ( collet or something similar) to grab the od of the valve assembly and the cylinder
4 guessing that it is right hand thread- metric of course
5 air arms was mfg ( did not know that) and that this model is likely a FN8 ( No model number visible while mounted in stock).
6 I have a small machine shop with big boy toys. making tools is easy. time is my enemy

I have a number of issues that need to be addressed on an FN19 Hawk. A few various searches on fb have not revealed the Falcon Owners group. Any chance you could link it or message me the link? Much appreciated!

The only FB group I know of. It's a private group, remove the spaces from the URL to go to the page.
The Falcon Owners forum was moved to Tapatalk, the forum admin will not let anyone new join. It looks abandoned anyway.
I found the tap talk group too. Too bad it seems dead. I had asked for membership there too
I had a Falcon pistol and found this when it had a leak. Very easy to work on.

Found this seal kit today. Any chance someone knows of a similar kit available from a US source?
