Yes, that is the exact adaptor i got. It is the airsoft innovations one too (airsplat happens to sell them). Just remeber youll need the little thing of oil (unless you already have some silicon oil). to oil the adapter and mags. (you need to oil the mags every 8 or so fills)
It is pricy, but think about it, its only a few cans of gas in price. Walmart is probably alot easier to go to for gas than say Jungle toy, or paying to have the gas shipped off the internet. and, like i said, its only $5 for two canisters (in the camping section). Which is an awesome deal, enough gas for a long time.
In the long run, its alot cheaper.
