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.
The HP Stak Pak is designed to work with QE designations that do not have a fixed site at the end, such as:

Regulator Service or Pressure Change
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.

Hi guy’s, after a few months of experimenting and going through trial and error, I finally hit the jackpot on a great combination to quiet down my HATSAN AIRMAX bark.
The QE shroud is good but when you pull out the baffles and put in the “HP Stak Pak For Hatsan QE”… ITS A TOTAL GAME CHANGER!!
The sound report on the gun is super quiet and the accuracy remains intact. But the hair pulling surprise is when you pair up this STAK PAK with a DONNYFL SUMO with a higher caliber on your existing one, you get a: TICK FART… I even thought my gun broke or I ran out of air.
My existing setup now is the QE shroud with the “HP Stak Pak For Hatsan QE” for quiet iguana hunting, and the DonnyFL SUMO paired with the QE adapter for extreme quiet barn pest control on Pigeons. They don’t even know what hit them.
I give this product a five star ⭐️⭐️⭐️⭐️⭐️
Happy shooting y’all.

Been trying to make my .30 Cal Hatsan Bully some what backyard friendly ever since I’ve had it. Have tried multiple configurations with the QE baffle systems and tried detuning it to 80 FPE to quiet it down with a DonnyFl Emperor to no avail. Was game to try these baffles as a last ditch effort or I was going to sell it. Got these put in 8 of the 10 baffles received ( wouldn’t take anymore with the included spring) there was a difference in t he report but not enough. Then put the DonnyFl Emperor on and wow what a difference. I know a lot of people say that with this or that lDC you can just hear the sound from the action. But with this set up, mine is just that. The sound from the action makes more noise than what’s coming out of the business end of the barrel. It is now just as quiet as my .30 Cal Wildcat. Thank you Haj.

This baffle pack for the hatsun is exactly if not more than as advertised. It made my bullboss very, very backyard family. And for the cost it was a super value. (you also get 2 neet-o stickers)
