you can, but it is not very good for your gun. You can only fire about 500 shots MAX at a time, because the gun will freeze up. Get your co2 tank Anti-Siphoned, and it'll work fine.

^not exactly true. maybe if you just sat there and fired constantly, a whole bottle of CO2, you'd freeze up but. I doubt it'll happen.

CO2 is bad for cockers because its dirty and corrosive. it wares down the internal o-rings so...EVENTUALY they'd need to be replaced. for an electronic cocker CO2 is absolutely un-usable. it'll destroy the solenoid.

you can use CO2, most people prefer N2, but get it anti syphyond to minimize the o-ring ware

GET IT ANTI SIPHONED OR GET AN HPA TANK sorry for caps too lazy to fix it

When I first got my autococker, I was still waiting for my Nitro tank to ship to me, and all I had currently was co2. People said it wouldn't really hurt the gun to shoot a couple shots. Well I screwed the co2 in and about 20 shots later my o-ring in the reg busted. I would highly recommend not putting co2 in your gun without a anit siphon.

**krum** · March 28th, 01:42 PM

prostock 05

**pballa12** · March 28th, 01:52 PM

my friend used co2 on his 04 stock. Worked fine no problems at all.

**sick_dawg** · March 28th, 04:30 PM

Co2 is completely fine on mech cockers. For electros, you need HPA so you don't get liquid in the solenoids and such, but mech cockers were originally designed to run on co2, and not a ton has changed since then. It is recommended that you get the co2 anti-siphoned so that you dont suck a ton of liquid through the gun all the time.

**xpdi** · March 28th, 08:44 PM

With the electro no dont use it. The mech cocker you will be fine using it, but it will just wear down on the gun a little faster.

**krum** · March 28th, 10:53 PM

Its funny how people are split on such things. I remember when I asked this same question in August I believe, and I had like 4-5 people tell me not to do it, because it would wear down the gun and could damage it. And of course some people said yes, so I did it anyways, and as I said above, my o-ring busted. So I sent it back to WGP to fix it and even they suggested you don't use co2 in the autococker.

But hey, if you want to then go ahead. Just make sure you know the damage could happen.

**sick_dawg** · March 28th, 11:50 PM

If you look in the manual it says that HPA works best, but it says that anti-siphon co2 is OK to use. At least that is what was in my 2k2 manual...

***Frozen Paint*** · March 29th, 01:10 AM

The truth about CO2 and cockers.

They were originaly designed to run off CO2, as long as you dont use CO2 with an electro cocker you should be fine. There have been some cases of blown o rings due to use with CO2, but then again dosen't every gun use o rings in some form or another? Anti-siphoned CO2 is the best way to go if your gonna use CO2, it dosent have to be, but results are best when it is. An alternative to anti-siphoning is using a remote and keeping your CO2 bottle in an upright position in your harness. Liquid CO2 is un-healthy for your cocker but it will not ruin it beyond repair (usualy just o rings.) No matter what you use to power your cocker, always regulate the input pressure to about 300 psi, (that's the pressure that your marker recieves.)

Any questions?

I've been running CO2 on cockers for 6 months and have had no problems. (my CO2 was anti-siphoned.)

**sick_dawg** · March 29th, 11:54 PM

Cockers were around for a bit before HPA was widely available/used. When they were designed, co2 was the most widely used gas, and therefore the cockers were designed to use them. At least that is what I have been told.

**krum** · March 30th, 01:40 AM

Ya but look at a picture of an old autococker...they were pretty different. The parts with today's guns *could* be more fragile to co2.

***Frozen Paint*** · March 30th, 06:25 PM

Sorry it's kinda long, theres just a lot of stuff.

If the parts on todays cockers are more seceptible to dammage from CO2, then that's a manufacturing flaw. No company in their right mind would change a product for the worse, in this case, making it more "fragile." Would you? It just dosent make sense. The thing that people are pishin and moaning about all the freaking time, are their o rings getting trashed. Correct me if I'm wrong, but I dont really think that the design of o rings has changed much since cockers originated. As I already stated, "don't all guns use o rings?" O rings are easily replaced and don't cost hardly anything compared to other parts.
To your comment about how post and pree 2K cockers look "pretty different" looks don't play a big part in how cockers preform. There are only a few differences between old cockers and new ones. The pneumatics is what every one is talking about. Those are the o rings they are blowing. Heres a list of things that have and have not changed: (theres a bit more info here just so you can get some learning and do some thunking)

"The following parts are the same for all years, and will fit on or in all cockers:
LPR
Three way
Grip frames
Valve
Jam nut
Vertical valve set screw
Hammer

Parts that were changed between 98 and 2k models, and are specific to post 2k cockers:
ASA
Front block screw OD was increased, and the front block was changed to match it.

The following changes were made in the '98 model:
New trigger plate for the sliding frame. Older frames requirer the old style plates, while new ones require the newer plates.
The velocity adjustment was threaded into the body instead of threaded into an adapted that was held in by the beaver tail screw.
Deeper valve chamber, requiring a longer valve spring.

The differences between mini and full bodies:
Pump Arm
Timing Rod

Very old stock rams, and most Clippard rams use a smaller thread on the ram shaft, and thus require a different pump arm than the now standard rams.

Back blocks only depend on the bolt being used, not the year of the gun it's self. There are three versions of bolts: Pre-2K, 2k+ and STO/Evo lengths. A pre-2k bolt can be used on any gun as long as it has a pre-2k back block, and the same goes for 2k+ versions.
STO/Evo length bolts and blocks have an over lap milled into the body, making them shorter. This is also called a "P" Block. Trust me, the people that call it a "Reverse P" block are wrong, and simply haven't been playing long enough to know that the only people that called anything a "Reverse P" block was KAPP when they needed a new name for their new, milled, but otherwise normal back block somewhere around 98 or 99."

Right feeds...heck left feeds, unadjustable front regs.. aluminum bolts yeah those were the days :P

I think I've seen every possible itteration of CO2 on a cocker back than, Remotes, 3.5/7/10/20 oz's mounted in every thinkable config

, I even knew a guy that had a 7oz mounted horizontally forward, and a second ASA that mounted a 20 oz to the back supposidly for greater "balance".

I actually still have a 99 PL cocker that runs just fine on CO2, though I never do anymore, a decent inline reg designed to handle CO2 tends to keep things running nicely.

***donalson*** · April 20th, 12:23 PM

i'd be willing to bet my e-cocker would be just fine w/ a palmers stab or impy max-flow and an anti-siphon

while you get the best preformance from a regulated HPA system... you can run any gun on co2 w/ the proper setup... i've known a few people who've run high ends (even trix's) on co2 w/ out a problem
