Liberty/Aspen/Avenger/Origin 1/2 x 20 #A50
$40.00

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.

HP Strip Stak Pak for Akela/Kratos
$40.00

INCLUDES NEW ENHANCED AIR STRIPPER DESIGN
For .177 and .22 Caliber Only

Strip Stak Pak for the Benjamin Akela and Kratos PCP’s
A nine-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 variable-sized 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. This kit is 100% compatible with the stock end cap or the DonnyFL A8 adapter.
The Air Stripper is threaded and comes with an o-ring and silicone grease for installation. The stock barrel shroud spring must be reused.

Replacement Air Stripper 0-ring is 14mm x 1.5mm

Umarex Gauntlet Strip Stak Pak (Bundle)
$45.00

Hajimoto Productions Strip Stak Pak for the Gauntlet 1 or 2. Not compatible with the Gauntlet .30 Caliber.
An efficient multiport polymer 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 HP Air stripper 2.0 comes with an o-ring. The kit also includes variable baffle chambers to help reduce both noise and turbulence in the airflow. The result is a more laminar air stream, which reduces projectile instability and, as a secondary benefit, reduces the report of the rifle.

BAFFLES CAN NOT BE USED WITH DONNYFL SHORT SHROUD
Because the Short Shroud is cut at a length that is a perfect fit for the air stripper and the spring. There is no room for the baffles in the DonnyFL Short Shroud.

Polymer Air Stripper comes with o-ring and silicone grease for installation.

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.

THIS ITEM IS NOT DESIGNED FOR THE GAUNTLET 30
IT HAS ITS OWN HAMMER PRELOAD ADJUSTER STOCK

The single largest performance increase modification item for the Gauntlet. The Super Tune Kit allows complete power adjustment, opening the possibility of higher or lower foot-pounds (FPE) for whatever the user desires. Do you need only 5FPE? No problem back off the adjustment using a 5/64″ allen wrench and you are only delivering 5FPE and will realize over 200 shots on a stock bottle fill of 3000PSI!

Want 27-30FPE for dropping that 20lb trash bandit, no problem, crank up the adjuster using a 5/64″ allen wrench and you instantly have the power necessary for either long range or high energy delivery on target. The use of a chronograph is required to know the rate of travel of the projectile. (Power examples given are the .22 caliber version Gauntlet 1)

For the Gauntlet 1 and Gauntlet 2. Be sure to select the proper generation, as there is a difference, and improperly selected kits are not returnable.
BE SURE TO SELECT THE CORRECT GENERATION GAUNTLET

Shipping

Shortly after you place your order for the service, we send you an order processing notification with a copy of your invoice. Shortly after that, you will receive a detailed notification with the shipping information to ship us your barrel/action/PCP for modification.
