CO2 tanks and butt-plate
Tanks in any size you like. Just click the tank below in the size you want. 4 oz ($17.99), 9 oz ($29.99), 12 oz ($34.99), 14 oz ($39.99), and 24 oz ($49.99) available. Butt-plate ($1.99) allows you to shoulder the tank better when used as a stock (does not fit 14 or 24 oz tanks)
When you're done or you get bored, you can just return to Ravi's Paintball Place.
