Search bar is still no good :( Quick question. To get rid of extra gas, can I just press the valve? In quick little bursts of course to avoid freezing anything. Am I going to damage the mag that way?

My other question is, is it a good idea to leave gas in the magazine? Some say no some say yes...

I'm getting the impression here that clearing the gas from the magazine just wastes gas.

Just press the valve, its not a big deal.
I think its safer to release all the gas, just incase and just to be safe.

I tend to keep gas inside the magazines at all times. It keeps the pressure on the o rings, and lubricate them at the same time. Since I don't dry fire, never store my magazines with bbs, and am extremely cautious about when I do pull the trigger when I fondle my guns, I can ensure that I don't accidentally shoot a round. I find no harm in keeping gas in the magazine as long as you store them in a safe, dry place and with no bbs in the bb channel.

I computed my LM4 magazines hold 1.3 ounces of green gas which means that 8 ounce can of gas doesn't go real far even if I get a couple of BB loads out of one gas charge.  Venting the gas just throws it away.  No reason I'm aware of to not save it until next time.

Green gas and propane are, of course, both flammable so any indoor magazine leakage has some liability.  I suspect a leaking magazine has about the same potential of happening as a meterorite striking my car on the way home from work tonight or winning the state lottery.  Yeah, it could happen.  But I ain't gonna worry about it!  And I don't store any magazines in the same room as my furnace or water heater or play with matches around them.  :)

Does it matter how much gas is left in the magazine? If I left it full wouldn't that damage it or something?

I l always leave gas in my mags now.  It accomplishes 3 things:
  • Saves on gas if the mag isn't leaking
  • Keeps things lubed inside
  • Let's you know if the mag is leaking.
I haven't really ever paid attention to how much gas is inside when storing.  I do partially charge my mags, if already empty, before storing too.

Good thread man.

I've had this same issue. I started hitting CQB arenas with my LM4 recently and realized I'm bringing home most of my magazines with full charge and a few loaded with bb's. I started trying to expend all the gas and ammo towards the end of my day at the arena that way I don't waste bb's or gas when discharging at home. Anyway before that idea, I had brought home all my magazines with charged gas and bb's. I had to shoot all my mags (which was painful since I use pricey .30g bbs) and then I vented the gas that was left after shooting. The next weekend half my magazines were leaking from the release valve of course, which I was worried was going to happen from venting them. I had to completely remove the release valves and hammer them with silicone lube and wrench them back in..so I missed a couple of the first games due to this. Luckily I bring a tool box with me everyone I go for games so I was good there..but it still sucked having to do that at the arena especially with the terribly designed valve tools. So with my lesson learned from now on I plan on either expending all the gas and bb's towards the end of a game and or keep gas in the magazines and store them safely.

I must say I'm impressed with KWA. It's 30 degrees out now and barely snowing. I just had to put "Engineered to outperform" to the test. I got a full mag and a few more shots after I put in more BBs :)

I leave the gas in my magazine as the times that I forget to do so the seals usuall dry out.

Also I forgot who but one of the KWA guys mentioned leaving the gas in the mag for a pretty long time and it didnt cause any issues or leak.

I saw a mag on a bench at KWA that had been filled for a few years if memory serves.  It was modified with a pressure gauge and the pressure was still at close to full.
