HP Stak Pak for Hatsan QE
Rated 5.00 out of 5
Original price was: $39.99.Current price is: $35.00.

Stak Pak for Hatsan QE shrouds (.357, .457, or QE screwed in place open sights Not Included)

Unscrew your shroud end cap, remove the two felt-covered stock baffle assemblies, remove the two aluminum stand-off chambers, and install the Hajimoto Stak Pak. No tools, no modifications, just a simple one-for-one swap! Some model Hatsans will use all the baffles others will need one less full-sized baffle, be sure to use both shorter baffles and leave out the full-sized one. If you need to leave one out, leave out the first full-sized baffle and then arrange the stack as shown in the packaging.

A ten-piece kit that directly replaces the two hair curler style baffles inside any Hatsan with a QE shroud system, excluding .357 & .457 models. The bundle has nine baffle chambers to help remove noise and turbulence in the air stream. The baffle stack rides on a high-tension compression spring allowing for a perfect fit for any Hatsan QE PCP, excluding .357, .457, and models with the fixed sight on the QE swell that are screwed into an internal ring.

The result is a more laminar air stream which reduces projectile instability and substantially changes the sound of the report of the rifle. This kit is 100% compatible with the stock end cap or the DonnyFL A24 adapter.

If your QE shroud has a fixed sight that is screwed to a ring that is inside the QE swell section of the shroud, you cannot use the HP STAK PAK.

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.

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.

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.
