Madbull 4 Round PB4 CO2 Capable Paintball Shell (0.68 inch)
(1) Spread out 4 rounds 0.68" paintballs. (RED gas is the best to shoot paintballs.)
(2) Easily load around 100 rounds B.B. and shoot out all at once. * (If you fill CO2, it will be extremely powerful!)
(3) Smoke Grenade: Fill baby powder into it and use it as a smoke grenade. * (HOT!!!)
(4) The best power source of NERF: Insert NERF into the launcher barrel and use the huge volume of gas as the power.

* You need to put a piece of paper of cotton in front of the grenade.
