Hi, I am about to order the KWA Kriss Vector. I was wondering if I should buy a propane adapter for this gun. Is it alright? Or will it waste my internals and make me replace everything? I want to do this because Green Gas is just to expensive for me. Thanks!

I would use green gas for the first 45 days of ownership so that you have your warranty. After your warranty expires, it is up to you. Let me just say this about propane...

KWA GBB guns are designed to run on Green gas. Any other gas such as propane will void your 45 day warranty. KWA tests have concluded that propane will do a number of bad things to your KWA GBB guns- if not maintained properly. First, using propane will increase felt recoil and wear out your internals faster. Since it is a dry gas, unlike green gas that has the right amount of silicon oil to lubricate, you will dry up your internals and put extra wear on your internals and risk damaging parts on your gun. Some people report success from using propane, KWA suggests green gas.

I use just propane no problem in my Kriss. with the amount of money you will save using propane you can buy a new kriss every year. :)

I've also found that the metal fill nozzles on green gas destroy the magazine's fill valve. So many people who use green gas end up having leaky mags within a week and come on the forums to yell at KWA. I have only ever used a AI plastic propane adapter, and I have never had one leaky mag or any problems people say propane causes.

I have been using propane on my KRISS almost exclusively. The only time I have only used gas other than propane was when someone inquired about a video of the KWA KRISS running on 134a (so I shot a video of it and posted it on youtube).

I have not had any issues with my gun using propane. I've put over 3000 rounds through my gun. Then again my gaming conditions may be different compared to other people. I've used my KRISS with propane in temperatures around 45-60 degrees.

I do check and make sure that my gun is properly lubed.

That would be a matter of personal preference but if you play more outdoors I would get the LM4.  Although the Kriss can be fielded outdoors it is an SMG which is more effective for CQB environments.  Just my opinion........................

So I can use Propane once my cans of Green Gas go out? The only problem I have with green gas is the price and how scare it is. Would it be better if I just get an adapter after I use the cans of green gas?

If it is a plastic adapter, you will field strip and clean the gun, not use Coleman propane, not use spray silicon and only use thick liquid stuff, and if you dont over-lube.

I would recommend to use green gas for the first 45 days of ownership so you don't void your warranty. After, you can you use whatever you like.

I've always used propane on all my guns and it never gave me any problems. Then again that's because I clean my guns very very often. Propane does gunk up your gun faster because it isn't as filtered as green gas is but then again it's all a matter of preference. I honestly prefer propane just because it is waaaaay cheaper.

Airsoft Taiwan they have a magazine adapter for WA, WE and KWA magazine, then you need a Polar Star's HP rig .... I lived in the midwest US, no way I can field a GBBR using green gas during winter time and this set up is the only way to do it ......

I don't know if there is any difference. But, to me, Coleman seems to have more additives. Worthington is the best and most adaptive to different temperartures and humidities. Everytime I use Coleman a huge cloud shoots out from every seem and it leaves a greasy slime all over the gun. Worthington's the best so far, can get it at Wally-World.

Good to know. Do most people use the Camping ones (green) or the one for torches (blue)?

So what is a good brand of green gas? Also, what about the Madbull Propane Adapter v2? Would that be good or bad?
