I have 2 more regulators on the way. A robert lane and an Altaros. That will give me 3 regulated tubes. One high power, one mid range and one low power. All 3 are different, the third bieng the audrius regulator. I'll do a review of all 3 to compare later.

Will all three be interchangeable between the Hatsan and the Pneuma?

Yes. Virtually the same gun. My Pneuma is .177.

Look forward to your review Joe. Regulators strike me as a really interesting piece of engineering. I've been sketching ideas for a double reg built into an extended 2240 valve - just pipe dreams but fun anyhow.

some of the most enjoyment in airgunning is from tinkering. Good luck.

What is a "double reg."?.... I built a reg. in to an extended front half of a Disco valve several years ago, using a Ninja piston, and it worked well for low power.... no plenum for high power shots, though....

Sorry, should have said "two stage". From what I've read there are advantages to ganging up two regulators instead of a single one. Two stage regulators have potentially less influence of input pressure on output pressure than single stage, at the expense of more droop (drop in pressure with increasing flow rate). I don't expect the droop to be much of an issue for a small bore air gun, so the better regulation of the two stage is appealing, as is the engineering challenge of making the thing. For sure, I'd make a single stage one first before trying a two stage, assuming I ever get around to this at all. As I'm sure you've noticed, my enthusiasm and ideas tend to run far ahead of any actual ability...

Ahhhh.... you're talking like a SCUBA reg where the pressure is dropping from 3000 psi to maybe 50, so they do it in 2 stages to ~ 150 psi over ambient water pressure, and then a second stage to water pressure.... I personally don't think it's necessary providing you tune the gun to be working at it's optimum for whatever your setpoint is.... as generally we are only dropping the pressure to 25-50% of the tank pressure....

Ah, now that would make sense. I hadn't considered that the extent of the pressure drop might be so different.
