I searched for any air-rig-related thread and I did not find what I was looking for, precisely.
Since the minimum allowed search string is 4 characters it is impossible to search for "air","rig","co2","hpa". I tried looking for the "expect" and "regulator" but nothing came out. I apologize in advance if this thread is a duplicate for another one. In that case feel free to delete it.

Hi everyone,

Preface:
I have been shooting an entire can of Top Gas and I am moving to my second one. My idea was to get close to depleting a second can of gas and then move to an external air rig for my Tanaka M40A1.

I am going to order the rig from AustinWolf at ClassicAirsoft but I have a couple questions I would like to ask, first. Hopefully these will make it easier for newbies like me to get a concise feel of what to expect from an external air rig.

My intent would be to make it as big as the rifle stock, to attach it or put it into my stock pouch. For this reason I will be using co2 cartridges, which are very common here in Italy, as well. HPA is very hard to find (almost impossible with that kind of threads to attach to the regulator) and I want to keep this rig as portable as possible.

I will probably try to get a tapped magazine from him, even if it is going to cost me more.

My questions:
1. I was thinking of getting a dual regulator air rig. Is it worth the extra? I think it is going to reduce the fps fluctuations even more.

2. This rig should improve accuracy by reducing a lot of variables involved in the gas release process. Am I right?

3. Will I be able to make the gun skirmishable (in mere terms of FPS chronoing) just by reducing the PSI reading on the second regulator?

4. Am I right that more PSI = more FPS in theory?

5. Apart from breaking or damaging the rifle, could a higher PSI value give me less FPS?

6. For target shooting only: let's say I find that my rifle can work at 170 PSI (just an example of a high reading) but the BBs are too light for the generated FPS, will my accuracy go back to normal (and therefore get an increase in effective range) by using heavier and heavier BBs (provided I find any)?

6b. If the above is true, Could I push my effective range for target practice a bit? How much should I expect (if somewhat predictable)?

7. Is it possible for a rifle to shoot stronger with less PSI than 100 or is it generally accepted that from 0 to 110PSI the relationship between PSI and FPS is direct (the more the PSI, the more the FPS)?

8. Would you use a short or long magazine type for the Tanaka rifle to use with an air rig? I was thinking a long one, this would allow me to keep the original one intact.

I don't think I have other questions for now :) Thanks!

Thanks MFC! (it's the acronym-frenzy day) :)

I've come to a point where I have to remove the heavy FPS fluctuations at all costs. When you start mastering the "guts feel" and the ammo, and the scope and all the other implied variables, having such a random element come into play like the fluctuations in gas pressure (and cooldown) is a real b*tch.

I agree with the above. The secondary rig is necessary, the first reg will drop the psi from 3000-3500 psi to 800psi ( the working area of paintball markers) so you need the other to drop it from 800 to about 150psi.
I'm going to build a rig for my classics but I'm not going to use it on my Tanaka's, that way I can still talk on how bad guns they are

Eheh thanks Wolf. I am curious to know one sniper rifle you would suggest for a plinker like me and another one for a sniper player..but this is going OT :)

Is 200PSI a o-ring/seal/whatever known killer? (I believe the striker spring has got to be on par with the pressure, otherwise it will strike dead and no gas will come out of the valve). I've seen some gauges go from 0 to 300, not that one has to go that high just because the gauge can read it :)

Actually you need that gauge (0-300psi) and you're right on the striker spring, you need a stiffer one, I have tried the one that comes with the G&G power pack but it didn't fit, so I'm looking for the King Arms.
The best skirmish sniper rifle so far is the RS SVD cause it's very good even in stock form it doesn't have the 100m range of the Tanaka but it's good enough and the BEST OF ALL is the Asahi WA2000, gas with NO fluctuation of the fps AT ALL!! Laser like accuracy at 70m this is the range I've tested so far

The Asahi is a real rare pearl! I wish I could give it a shot (literally lol).

Wolf, you said I am going to need a 0-300 gauge because I might go over 200 PSI? Or did you mean "you need some kind of gauge to read the PSI you are getting?"

Thanks ;)

No you won't be able to go beyond 170psi ( I guess) but most of the gauge are at 0-300, the Asahi I have came with a brand new Palmer's reg ant the gauge was 0-600 but you can fine tune it only above 200psi!!
Make sure to order your rig correctly cause Mcmaster won't ship outside US in case you'd like something else or to add something afterwards.

Thanks for the info. You mean AustinWolf won't ship outside of the US? If so, I am pretty much done :)

I would also need him to put the required items for tapping the magazine (fittings, drill head etc.)

No Austinwolf ships everywhere Mcmaster is a store which specializes on hoses and other pneumatic stuff.
Tell him what you want to do and ask him to send everything.

Ah sorry, I thought it was another nick or something. Got it, very clear. I am going to tell him what I need, trying to consider a 360 degrees analysis on the matter.

If the can get me a magazine and tap it I'd be more than happy to pay the extra. Otherwise I'll get the required tools and tap it myself. Either way it has to be a one time deal where I get all I need and that's it.
