premise: Here is a Spyder Victor 2 paintball set , a bag of 500 paintballs , and a CO2 tank that has only been used for 500 paintballs . I used this for target practice at my friends lake cabin twice and have n't used it since . It is in perfect condition with no scratches that i can find . The CO2 tank is very full and i believe it is refillable . What is the narrator likely trying to do with the paintball set ?
hypothesis: Trying to offer it for sale
