Many people say that the f4 is no good because of the trigger and the
barrel. I think that the barrel is just fine and that you would never need to
do anything to it. The paint that I use is Nelson and it does fine because I
have gone through about 3 cases and have never busted a ball. The accuracy is
fine at about 150 feet and then the ball starts to drop if you do not have the
velocity turned up high enough. One thing that I would recommend doing is
getting a wood filer and filing the sharp edges on the trigger. I have had
many blisters from that. Overall this is a great marker and I would recommend
it to anyone on a budget. It is about the level of a spyder elite but better
than a standard spyder. I prefer bottomline setup although you can also use
vertical by using an allen wrench to remove 2 screws and then unscrew the
hose. I would also get a 12 oz. aluminum tank because it has a very CO2
valve.
