Thanks for the help on the gear guys and yes the VSR copy is manufactured by Swiss Arms, a cheap knock off C02 version, the canister goes in the bolt out of the box and they shoot over 800 FPS when purchased they are meant to be downgraded but mine wasn't done enough so I couldn't use it I really appreciate the gear help though. Also I really need to get buying some real stuff instead of cheap crap off Amazon I had a viper ubacs shirt and I hated the arms, attached or detached they felt so bulky so I gave it away but I now will get ordering.
