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:

5/8″-18UNF Threaded Unit
NOTE: THE NINJA FLEX REGULATOR HAS A LIMITED INVENTORY
Ninja Paintballs’ Flex Reg with Custom Gauntlet Configuration.
Say goodbye to only one fixed output pressure!
The user has an 800 – 1000 psi adjustment swing!
Requires minor forestock modification.
The regulator thread is 5/8-18UNF (Bottle Thread) and Typical Paintball Threads of .825-14 NGO (PCP Thread).
Please note the Flex regulator can be used with any Air, Co2, or Nitrogen driven air gun not just the Gauntlet, providing it has the correct threading.
The Ninja Flex regulator is available in any 900 psi spread to a maximum of 3100 psi output. For the Gauntlet, select the proper configuration.
If you select the Custom Configuration, you will need to use the NOTES above to communicate what you want the maximum output to be. Please note that the highest output the Flex Regulator can be configured for is 3100 PSI, but we can build it to any number below that. Example, a user wants the maximum output of their Flex regulator to be 2800, we will build the regulator so that the adjustable range of that build is 1800 to 2800PSI.
How to read the below configurations
Example: Flex Reg .22 | 4500/1600 to 2400 psi
Flex Reg .22 = Regulator Type for .22 caliber

FX shows that they are able to innovate not just within airguns themselves, but in other areas of the shooting sports. The FX No Limit scope rings are perfect for long-range shooting as you can vertically adjust and angle your mounts so you can always find the sweet spot on your scope. These rings are also very useful if you need to have your scope higher off the receiver to allow for oversized magazines or scope camera setups.
You will want these rings if you are planning on using my Expanded Magazine.

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)

Where do you get the initial nut you put in the barrel and the tool to tighten it in there?
