I bought this at a local airsoft/paintball store and it really works like its supposed to. Alot of the reviews say that when they charge the gun the valve stays open and sprays propane everywhere. It does. But don't let it discourage you from buying it. All you have to do is unscrew the adapter quickly and dont be afraid of it. I dont get why someone rated this one star because of this problem, its a very easy fix. I have the kjw mk1 carbine and propane works just as well a green gas. I really dont get why people say that green gas ruins your gun because it doesnt. Over all great adapter and will save you money in the long run.
Works like its supposed to.
Easy to use
Cheap in the long run
Will leak propane, just unscrew it quick
Propane cans bigger and heavier than green gas cans
Expensive if you only airsoft once in a while of dont use gas alot
