Venting CO2 Carbine Mags

Postby Kendo » Mon Apr 11, 2016 5:11 pm

Cards on the table, lads: I had the carbine out at the weekend for a skirmish and all five mags are pissing gas everywhere. All are CO2, with fresh bulbs, and all worked flawlessly in the house literally a day previous; pulling the trigger fires the first round, but the bolt does not reciprocate and a long, sighing hiss follows as the CO2 empties.

None of the mags are leaking, and while it was certainly brisk in the morning, it was well above freezing (I tried it at lunch time when it had 'warmed up' but to no avail). My TM 1911 on the weakest gas known to man managed to cycle just fine.

Answers on a postcard, please. :banghead:

They don't like cool weather, let alone cold.

The nozzle needs to be lubed lightly. They seem to like silicone oil rather than grease. But not too much. I also stripped the nozzle down in order to get a little oil into the piston. This helped a lot.

On that note: you will see a little pin that passes straight through the nozzle. This will work loose. It will jam. It will cause you to swear a lot! A drop of superglue helps. (It won't be impossible to remove as the nozzle is polypropylene or polyethylene.

The weird thing with the nozzle on these is that it relies on a face to face contact with the breech rather than the usual nozzle that feeds into a hop rubber. I think that the expanding gas, on anything but warm days, causes the rubber face to harden. Then it fails to seal and it vents.

I have two ASG/Marushin M1 carbines, Chris has one too. (He sold his spare).

The magazines can be adapted to hold an extra 5 or 6 BBs.
If you are lucky, you will get 1 magazine (around 25bbs) per CO2 bulb. :(

When working, they are fun to shoot, but should be used at short-medium range.

Fitting a real wood stock is not difficult if you have a Dremel. (You need to shave some wood off the inside of the stock)


I believe that the KA is a clone of the Marushin from what I have read. The nozzle looks identical.

Yeah... still. Would rather get one of the new M3A1 Greasers in this case, if only I can figure out why the S&T and Snowwolf models have such widely different prices for guns that appear identical in design and manufacturing...

Yeah, I've got an ASG-branded Marushin M1 Carbine, and it does the same as this on anything other than a warm day. On a warm day, it shoots fine, so long as you're not too trigger-happy: if you are, I find it quickly gets to that point where the action doesn't fully cycle and then it vents all the rest oft eh CO2, which is often a fair bit of it - quite depressing really! As has been said, they're good fun on a warm day but are best used at medium ranges.

I'd also agree with the ICS Greasugun being a superb choice if you want something small and light: they have superb range and accuracy right out of the box, and as has been said you can get mid or hi-cap mags for them, and the mids are 140 rounds so you don't need too many either. The only thing to watch for is that you get a lipo which fits - it's a small old battery compartment and I have bought too-big batteries a couple of times, which thankfully I can just use on other things instead. But ours gets used at most of our regular airsoft games, it's every bit as good as everyone and his dog's M4. :)
