Regulator Service or Pressure Change
Regulator Service or Pressure Change
$45.00

This is a service to repair, test, leak test, adjust or increase the output pressure of a Umarex Gauntlet 1 or 2, regulator to a customer’s requested output. The regulator will be tested and calibrated to within +/- 75 PSI. Parts such as Gauges, Burst discs, Bonnets, Pistons, Caps, or Regulator bodies are not included. If parts are determined to be required to repair the regulator, pricing will be determined, quoted, and will need to be paid prior to the return of the regulator.

Please note that if you have a Taiwan-produced regulator, which is the regulator that is located at the top of the photo, there are very limited corrections that can be made to these units and you may end up needing a new regulator. Please use the notes area to provide the Generation and caliber of the rifle. Also, give as much detail as possible of the issue or the requested pressure output and so forth.

Once the order is physically reviewed, you will receive a second notification with details associated with packaging and shipping the items in for service.

When you place the order for the above-described service, you will receive an order processing notification. Shortly after that, you will receive a detailed notification with the shipping information for you to ship us your regulator or regulator and tank assembly.

This service is not a hydro test of the tank/bottle and is focused only on the regulator’s functionality and visual inspection assemblies.

Please note that this service is not associated with any manufacturer’s warranty, so please be sure to exhaust all warranty options prior to sending us your regulator for service as our working on the part voids any manufacturer-provided warranties.

Strip Stak Pak for the Artemis PP750
A five (5) piece kit that includes an efficient multiport air stripper that strips and channels air away from the pellet to allow for a more stable and less turbulent pellet launch from the muzzle. The kit also provides baffle chambers to help remove both noise and turbulence in the air stream. The end result is a more laminar air stream which reduces projectile instability and as a secondary benefit, reduces the report of the rifle.
Air Stripper comes with o-ring and silicone grease for installation. Not available for Canada

UPDATE: The newer avengers have a screw-on barrel shroud and an end cap that is a two-piece unscrewable but the STP still fits and works without an issue. unscrew the shroud rather than the little screw shown in the video and simply unscrew the baffle washer array off the end cap and you are good to go.
