Ninja’s premium SL2 series of HPA tanks are built with serious paintball players in mind. SL2 tanks weigh less than any other tank of the same size, making them popular among competitive and hardcore scenario players. The 77/4500 SL2 tanks are most popular with players who want to get an extra pod or two out of each tank fill, which can often mean the difference between winning or losing those long, grindy points. This tank features Ninja's Ultralite regulator, which comes set to an output pressure of 800psi, and can be lowered to either 650psi or 500psi.
