alot of you complain about having extra co2 in your gun, well you people are dumb$hits. duh theres co2 left in your gun its not magic, it cant suck the air out when you turn it off. that has to do with the way the gun is made and how much air is in it at the a time. to all you little girls winning about it just take the gun with the extra air in it, hold it waist high, spin it around, and fire that should take care of the extra air problem.
an awsome purchase i would definatly get one saves a ton of air
