The Tippmann paintball guns are some of the best made guns on the  market and sometimes used in the army for practice because of their durability. The Tippmann guns are the best guns because they are durable and they have accuracy, they don't have the paintballs break in  your barrel, and the reliability of the gun is what you need and these guns have all of them. (Below-upgrades to the custom98 and to the flatline barrel system.)
