Black Spyder Shutter, home trigger mod, 20 oz. on/off, smart parts all american 2002 barrel, sticky grips
It only has 1/4 turn to turn it on/off, so you can do it very quickly if you need to. it saves air, you get a higher flow rate, there is no pin to break in the valve, it comes in a bunch of colors, smart parts rules! (It actually can be used as a fire extinguisher)
Not a thing
This is well worth your money, especially if your pin valve is leaking. go to your nearest paintball dealer and order it. have an airsmith install it so you don't screw it up.
