Description: Ninja LPR 42 Adjustable Regulator Years ago we made a product which was a low pressure regulator for the paintball industry. When we were asked by Airsofters for a more efficient, more maintainable and cost effective solution we came out with our Ninja LPR. The Ninja LPR is adjustable between 0-130 PSI with a safety pressure relief valve which will start to vent at 130psi so you do not damage your marker. With the Ninja LPR you can use any air system with up to a 1000 PSI output to power the LPR, no need to get a special regulator, use the reg you have! Ninja LPR's are fully rebuildable and come with the made in USA quality and support which you have come to expect from Ninja.
