leaking CO2 on brand new gun

[gpunches]

Just bought 2 new spyder aggressor paintball guns for my sons for Christmas and the first time plugged in the CO2 it was leaking out everywhere with both of the guns!! Has anybody else has this problem??

the aggressor is an old gun, so if it's 'new' im guessing it hasnt had any use and for as old as it is, the o-rings are probably bad

oil the rings, change if need be. Cock the marker before you attach the Co2.
