I have a madbull co2 charger and the pressure is adjustable.I will try to do what I seen other people do with the m1100 , take the stock out and replace it with a ATI foldable stock and pull the gas hose to the stock and attach the co2 charger there.With the m870 I will atleast try to change the receiver in to G&P m870 metal receiver/outer barrel.Thanks for the information and let me know if you come up with upgrade parts/tips.

@pieruaivo If you are using a regulated CO2 setup (I had one on my Tanaka M40), it should work fine if left below 120 or so psi (and be more consistent than propane), but I personally don't think it's worth the trouble. You can improve the consistency, but I don't trust the internals to hold up to any attempts to increase performance. You would have to basically replace every single component (including the receiver frame/shell) or it will just break the next weakest link.

@tunabreath I have seen people hook up co2 air rigs straight to m1100 online.I don't know if they modified in other ways.

@pieruaivo I wouldn't recommend it. Green gas, maybe, but definitely not CO2. The bolt rails/lugs are cast pot metal and won't hold up to it (hence why I put made a pump arm to be printed in the stainless steel as well, mine cracked the ends of the bolt holes off).

@tunabreath well I just ordered one to try it out. BTW do you have upgraded your m1100/m870 power in anyway? I just bought them both, I have read about them but I havent found any solid answers if they can handle green gas or co2 ?

@pieruaivo I'm not sure, I don't have access to a basic M1100 to compare with.

@tunabreath does this work for the basic maruzen m1100 also?
