Polarstar MRS Reg/42 in line

Category: SKU: 8464 Tag: Brand:


This ultra 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. Oversized 4mm piston bore for extremely high flow and refresh rate even at only 40psi.

  • Integral tournament lock can be secured by a standard zip-tie.
  • Adjustable output pressure from 40 PSI to 145 PSI (This is the standard configuration)
  • Integral on/off valve eliminates the need for a separate UFA.
  • Compatible with standard HPA as well as SLP Tanks.
