The Ultra Light Regulator from Ninja is a compact, very constant, high-quality HP (800 PSI) regulator, suitable for all paintball air systems or compressed air bottles.
What distinguishes this from the standard regulator, apart from the price, is that the UL Reg., as its name suggests, is a bit lighter.
Since the setup of the paintball marker tries to save every unnecessary gram anyway, a fine solution.... not necessarily decisive in the fight, but again some weight is saved.
