I used one of these last week at a match and it was a BEAST!! This is one of those must-haves to be an effective grenadier. This is because it has far more range and power from what i'm guessing is the CO2 instead of Green Gas. With this shell a grenade launcher is actually useful! The best part about this is that it actually has a kick to it when fired! Be advised at close range because i have seen this embed bbs into tac vests. The only issue with it that i noticed is that the triggering pad at the bottom is relatively "touchy" so be careful when handling it.
Makes a Launcher Useful
Takes CO2 which is much cheaper than Green Gas
Trigger Pad is kind of touchy
Not optimal for "safe" CQC situations
