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.
I wrote an article on the regulator change back in 2019, read all about HERE
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.

Intended for higher power builds
This part replaces part #19 and allows for greater valve dwell producing more power to be produced at higher regulator pressure settings.
The .22 caliber HTVS for the Generation 1 Gauntlet fits both the .177 and .22. Do not order Generation 1 HTVS for the Generation 2 Gauntlet, they are not the same
Part fits either the original Gauntlet or the Gauntlet 2
You must apply a liberal amount of silicone grease or other synthetic lube on the air strippers o-ring. Failure to do so will cause the o-ring to grip the dry interior of the shroud and cause damage to and break the air stripper. Please read the provided instructions.
Air Stripper comes with o-ring and silicone grease for installation.
Fits the Nova Liberty, Aspen, AV Avenger, and Origin PCP’s
This is a direct replacement end cap that when installed provides 1/2 x 20 UNF threads to allow the installation of your favorite moderator or suppressor. If you are looking for a better and stiffer barrel to barrel shroud connection that helps eliminate point-of-impact changes or projectile clipping issues, consider going with the A70 Adapter which essentially marries the barrel to the shroud.
If you are a Hajimoto Productions Strip Stak Pak (SSP) user, then stick with the A50 because the A70 will not work with the SSP.
