Spyder Xtra All American Barrel Empire ReLoader 20 oz Co2 w/ on/off
It doesnt leak
Easy to use
Easy on O-rings
When i first bought my co2 tank it didnt have the on/off valve and maybe it was just me but when i unscrewed it from my marker it seemed to waste a lot of co2. I went out and bought the on/off valve and it worked great. for only 30bucks it did exactly what i wanted... all you do is tunr it off shoot a couple times and there is no co2 left in the gun.
Does exactly what it is supposed to without leaking
