What is G&G Gas Bolt Conversion Kit for Maruzen APS2?
 

Hey,

I was browsing the web today and saw a G&G Gas Bolt Conversion Kit for Maruzen APS2?! That's so cool! Has anyone ever given this a try? How does it perform? Where do you fill the gas? How many shot per fill? Where does the gas store? Also if anyone know where I can find a diagram of the kit, that would be amazing!
