Here is a preview video of the upcoming Wolverine Airsoft Wraith CO2 Stock... "The Wolverine Airsoft Wraith: CO2 Stock gives you the great performance of HPA without the line. Perhaps the biggest resistance to HPA that we have heard from people is that they do not want to carry around a tank or have a line coming out of their gun. The Wraith: CO2 stock eliminates both of those!

Our Evolution Series SMP gets approx. 200 shots/cartridge and with our quick-lock cap, it is easy to change cartridges on the fly."
