Updated August 2016 - This is the unofficial V2 edition with a much higher refresh rate. This version can handle extremely high ROF HPA setups now (30+ RPS) with no refresh issues. Rebuilt and redesigned for you crazy Polarstar F1 tweakers.The Ninja LPR-36 Regulator Kit w/ 36 inch hose Line. A ultra high quality complete HPA airsoft rig setup for use with Polarstar and Wolverine systems - along with any kind of HPA air tank (SLP and regular Paintball). Air hose is big bore braided for the best airflow. Just add an engine and tank!The Ninja LPR Regulator kit is unique in that it doesn't require a SLP tank to use. It can use both regular SLP HPA and high pressure (800 PSI) paintball tanks alike! The incoming pressure can be up to 1000 PSI. The LPR-42 then reduces this pressure down to acceptable levels for use in airsoft engines like Polarstar, Wolverine, etc.
