How to run a mag on co2

[goldengun5]

HI, i'm new to the Mag world. I just got a used 68 classic, it has a front pmi reg. It previously used nitro, I adjusted the reg on the valve to shot at 290fps.

I hear that its not good to run a mag on co2, nitro is a little out of my price range and kinda hard to find fills for. How can i run this mag on co2, i was thinking of puting a good x chamber and anti-siphon, what about a palmer? Any ideas or thoughts would be apreciated

[smilestyler]

Those are good ideas. You could also use a remote hose.

So are you saying you have a pmi reg on the front as a foregrip? If so, that should be sufficient and just put a CO2 tank on a drop forward. If you have the old classic valve, it will run okay on CO2. Nitro or CompAir is generally cleaner, but if you can't get it, you are stuck.

If that doesn't work for you, the palmer stuff is top of the line. On expansion chambers, get the most expansion chambered one that you can find. I have seen some that are 6 chambers. You don't have your location, so can't tell where you are, but farther north is worse for CO2...

i live in WA so its fairly cold

in my bed room i had a co2 on a remote and just sat it on the floor, i fired off the whole tank, yes i was really board, and the tank got icy cold and was dripping wet, i felt the mag valve and it was barely even cold, and no leaking/freezing of orings. if that helps any.

They now have pre-set nitro tanks for $80 and fits CO2 bottom line.

i know but here fills are way spendy, and id probably need at least 2 of those tanks. So co2 is the way to go for me

My old mag did fine when I had CO2. Ran it like this:

CO2--->Gas Thru foregrip--->Classic Valve

Played *alot* in the winter with it, in very cold temps. In the -10 - 10c range.

I can honestly say I never once had a problem with it in the cold. I wasn't a member of the ao boards at the time I had this setup so it came as a shock to me when I got here and saw people having issues with CO2.

okay just shot my mag wit co2, after some real long strings of shots it froze up and leaked out the barrel. How can i stop this while still using co2? Should i adjust my front reg? gun works great other than the freezing

[Carnage]

Not sure if this has been said but you can place the co2 tank in your vertical adapter? I seen some co2 mags like this.

Couple questions Why would you need 2 nitro tanks and what is spendy for fills. I pay 1.00 per 1000lbs on field fills. You need to move to the mid west
When I shot co2 I had a 3oz bottle expansion with an anti syphon and a 20 oz main with anti syphon. What a beast. The 3 oz was mounted over the 20 off bottom of grip.
I would have to turn the gun upside down to suck liquid.
That is the goal to keep liquid out of the valve.

You dont need a reg till it starts getting warm. The pressure in a co2 tank at room temp is around 1200psi. Now chill it down and watch the pressure drop warm it up and watch it rise. If you want 100 shot strings at speed you wont get it with co2. I put my gun down in a tourny once by freezing down the tank. The mag shot greet{no liquid in valve} but once the bottle froze i was only shooting like 150fps. Had to warm the bottle back up under my arm pit to get back up to speed.
Use anti siphon and expansion chamber to keep liquid out of valve and control your rate of fire so you dont chill the bottle to much.
Hope this helps ya

Just re read your last post your valve is freezing cause youre getting liquid in it. KEEP THE LIQUID OUT. Slow down your rate of fire. Remember the temperture thing. Your Mag will rock on co2 if you shoot it right.

ok im defintaly gettin anti-siphon, but should i ditch the reg and get a x-chamber?

[sime]

while i don't know much about the PMI reg, i do know that generally a reg will do far more for preventing liquid then an expansion chamber.....

that being said, i am curious as to the output of that reg, as we all know (or should know) to work effectivly, there should be about a 200psi spread between regs (which half woried me when i first read your post, the guy you got it from was triple regulating it.....). so try and get the PMI to about 700psi output, then use the mag's to set velocity.

that MAY have been the issue with it locking up, too low of an input pressure into the mag's valve.

and remember, mags have been around a lot longer then HPA, though as said, there are some steps you can take.

first is definatly that anti syphon tank (if you want to run an on-gun setup). secondly, a reg (with the plamer's WAY up there in the "liquid eating thang") with those 2 things, you'll be as good as it gets.

i hope that all made sence, i'm still a bit hungover i think.

cheers

ok great, how do i tell wether the reg is at 700 psi, it doesn't have a guage. How do i even adjust the pmi in line, is that the thing on the bottom? thanks everyone
