Regular price $142

This compact regulator stands just 3 inches tall and threads directly onto the HPA tank. In so doing it eliminates the need for a separate UFA and keeps your air rig profile to a minimum. What sets this regulator apart from competing models is its integral on/off valve. This enables you to depressurize the system prior to unscrewing it from the tank to elevate wear and possible damage on the tank threads and o-ring.

  • Adjustable output pressure from 40psi to 145psi (standard configuration).
  • Optional High Pressure Spring boots maximum pressure to ~200psi.
  • Oversized 4mm piston bore for extremely high flow and refresh rate even at only 40psi.
  • Integral tournament lock can be secured with a standard zip-tie. Compatible with standard HPA as well as SLP tanks.
  • HP Spring Not Included

Min Output Pressure 40 PSI
Max Output Pressure 145 PSI (~200 PSI with HP Spring, p/n 10000556)

Warranty Information 1 Year Limited Warranty


**Available as "Air Rigs" or stand alone "Regulators". The Air Rig includes the regulator, air line and male QD fitting assembly which is everything required to connect one of our HPA engines to an HPA tank. The regulator is just the regulator part of the air rig and requires an air line and QD fitting to be purchased separately if not already in your possession.
