Ok, first gun, sits on ass, lazy, bored, video games. I have played LOTS of paintball and know the market pretty fuckin' well for any gun, any part anything. I had own real business, I fixed guns for a long time and still do.

I would suggest a Tippmann 98Custom or a mechanical Spyder which you can get BOTH at Wal-Mart. Do NOT buy Brass Eagle, godamn the most worthless marker ever. Do NOT buy Viewloader Markers, same as brass Eagle. For starters, get him one of the two I mentioned, but only mechanical as electric markers "chop" paint(which means the balls break in the chamber and up through the loader). So get a mechanical, with a normal gravity hopper($3), and a 14-20 oz CO2 tank, runs about 100$ for all of it + a mask which can be included or bought separately for about 20$.
