Hatsan Hydra Mods

[Hatsanlvr1980]

Hi, I have some questions regarding the air capacity of the hydra.
Is it possible to change the air tube?
If so, which one is a direct fit?
What about a Huma regulator?
I don't mind disassembly and reassembly for tuning.
I'll be glad if someone could help,
I have the .22 and .25 barrels
Thanks

I own both the Hydra(s) in .22 and .25 as well. One was a refurb and I am still correcting it ( currently disassembled). I also own the Hatsan Flash in .25, and all guns I am using Huma regulators. One benefit is it quiets the "ping" of the hammer strike which is a desirable side effect. I measured the tubes once and thought they were different sizes when I did. PM me and I will give you the measurements.
