Which does work

Interesting. Any idea how it actually functions?

They actually have a LP bleed off that is hidden behind the gauge. It functions like your LP burst disc, the usual culprit for the LP disc blowing is worn out orings on your piston (well that I have seen working in the shop).
I have the ones with the HP burst disc only and never had a problem with my macroline blowing at all. I do clean them from time to time and lube the seals.

I could see if the seat gets damaged it causing a problem and there being a spike down the reg. I remember talking to the old techs for GA about this and I cannot remember what they said about that.

I now feel more informed. Thank you guys!

They talk about a High Pressure Burst Disc at 7.5K and a Low Pressure at 1.8K but how this is arranged in the actual regulator is unclear as you can only see one burst disc port. There is an entry in the manual that implies the LP burst disc is behind the low pressure gauge, "3. Leak at low end safety vent behind gauge.". I can not find reference to this in any of the other documentation especially the drawing.

Edit: I've sent a request to Guerrilla Air/Tiberius for clarification. Now to wait and see.

In my experience, it doesn't.

A member here on MCB shipped me a brand-new (he said) Myth reg- the smaller kind, without the LP burst disc. What I didn't know was that it was missing the piston seat. When I used the tank on my Phantom, the reg free-flowed. The bleed hole didn't blow, but the Phantom's stainless hardline did- right out of its compression fitting. I ended up getting some wicked poison ivy blisters fishing around for all fittings that landed in the chrono station.

That wasn't the first time I've had trouble with a Myth reg. I had another one (used) that where the output pressure would spike over 1000psi when it was filled, then slowly creep back down. I could watch this on my Phantom's valvebody gauge. Turned out the piston seat wasn't missing on that one, just worn.

To Guerrilla's credit, when I mentioned this problem on MCB they happened to read my posts and sent me, free of charge, an entirely new piston and seal set. I used those parts to repair both regulators and they've functioned perfectly since then, but I am keeping my eye on them.

Myth regs are okay, I've got a few of em but I find the shortness of them is often more a curse than a blessing. I got 3 Ninja regs for my 8CI tanks and they are very good quality.

For me it depends on the gun and tank. The super-short Myth reg makes my 68ci tanks extra-comfortable with my Sniper, but seems slightly too short on my Ion. My first Myth actually came on my 13ci tank, and it makes that one much too short to be usable as a stock. As for my 22ci tank, I wouldn't even consider using it without the Myth reg.

[ApoC_101]

Ah yea, I use my 22ci with myth reg and also wouldn't use anything else... tank would be too damn long for any setup. The two guns I use the 22ci on have rail mounted ASAs set to the correct length to clear the guage when screwing the myth reg in, so no issue... problem arises when it's my last tank with air in it, and another gun wants to get used

I guess, what it comes down to: Myth regs are a good addition to your air supplies, but you should definitely have another tank with a longer reg on it if not all your guns have lots of ASA clearance.

Just remember, comfort is the key issue when dealing with 4500 psi pressure vessels placed 3" away from your face.

Honestly, after all the negative press around the Myth regulator, and some peculiar design choices with the low pressure fail-safe, I have no faith it and I am actually a little afraid to use it.

I had a Myth, it wouldn't keep up with a 4 shot burst out of my A5, so I got rid of it for a Ninja.
