AI Propane and Dustcan Adaptors
 

I've heard very good things about both of these products.

Has anyone done a performance test for the duster air vs propane?

Duster and propane are different types of gas, meant to be used for different guns. Duster is significantly weaker than propane.

I know that Green and propane are the same. I also know that duster air is weaker than propane. What I wanted to know is how much weaker?

In a stock Tokyo Marui Hi-Capa 5.1, duster shoots approximately 235, whereas green gas shoots approximately 300fps

I've never had a chrony to be able to test, but I'm not surprised at these numbers at all. I fired both my TM P226 and KSC Glock 17 on both duster and propane, and the difference was like night and day. Both those guns have metal slides now, so duster isn't an option anymore.

I know my 2 WA pistols use duster, and they just feel horribly weak when I fire them, even though I know that they're quality guns that look and feel great. I wouldn't see myself fielding either of those pistols. They get used for plinking in my basement.
