Do you have the SI (Spartan Imports) version?
They are Green Gas / Propane friendly. This is more of a fact with the Marushin M1 Garand than it is with the Marushin M2 Carbine.
You can use propane / green gas in the mags if you have the SI version. it'll clearly read SI version in the manual and on the box.
HOWEVER, if you fire EITHER version (Duster or Green Gas) of the M2 in full auto and empty the entire magazine of 15 rounds you will eventually break the bolt. You'll be able to tell that the bolt is going to break as the black metal will start to have grey marks on it showing where it will crack.The stock bolt (part #7) is not made of a quality metal. A replacement quality bolt will run you over $100 U$D if you are fortunate to even find one in stock.
SIMPLY PUT, TO AVOID DAMAGING YOUR GUN, AVOID FREQUENT USE OF THE FULL AUTO FEATURE ON THE MARUSHIN M2.
The M2 manual does have some caution in its contents about the full auto feature written in it. But I'd just not bother with the full auto feature except to see how it works. Definitely do not empty a mag on continuous full auto.
If you are filling the mags make sure it's at least room temperature and wait a minimum of 15 minutes before using as the mags cool down pretty good.
