SIG Sauer MPX / MCX High Pressure Air (HPA) Remote Upgrade. Complete with HPA Adaptor, 0.8L 3000 PSI Bottle, Remote Line with Slide Check Valve, and a Quick Coupler Socket for refilling the bottle. Weighing in at only 1300g you will hardly notice this in your back pack.
Following up on customer feedback, and further product research, we have concluded that although fast fire capability is possible at 850PSI, a drop in performance is also noted when running at the lower 750 – 850 psi regulator output, so we now supply our kit with a NEW 1100 psi Output Regulator.
