User adjustable M18 regulator
Huben Power Black Hawk Pro
Select options$150.00Original price was: $150.00.$130.00Current price is: $130.00.The Huben Power Black Hawk Pro is a very stable, high-flow M18 threaded adjustable regulator that allows the user to adjust the output pressure to what is required for the application. The quality of materials and craftsmanship is top-tier. We tested these regulators here at Hajimoto Productions and the standard deviation was so low it was incredible.
Works with but is not limited to the following:
Umarex Gauntlets, Skout Evo 30, Skout Evo 25, and Skout Epoch 22FEATURES
- Rotational bonnet allows for exact thread indexing/clocking of the regulator to the PCP.
- Streamline and slim structural design
- Thread: Bottle = M18*1.5 and PCP = G1/2-14
- Max up to 4500psi high-pressure gauge input.
- Regulating output pressure range 500psi~3000psi
- Comes with a standard 8mm quick disconnect male foster fitting for filling.
- Dust caps may be green or black at random.
- The regulator has a high airflow rate, is lightweight, easy to operate, rebuildable, and designed for use with HPA/CO2.
- Please note: When storing high-pressure for a long period of time, creep phenomenon (an increase in output pressure) may occur. After the creep phenomenon occurs, the original output pressure will be restored after one shot.
SKOUT USERS*
This regulator does not have a pin on the top of the regulator. This means EPOCH owners are ok, but EVO cannot use this regulator. -

A complete Haji-Notos Power Plant Combo. It allows for precise power adjustment allowing the Notos to deliver only the power required for the situation. If you want to shoot pest birds in a barn or feed house, you can dial it back to fly pellets as low as 400 ft/s, or if you are hunting grey squirrels and want to deliver a JSB Hades 15.89 gr at over 750 ft/s you can do that too.
FEATURES
- Includes ) 0.3L Long, 0.3L Short, 0.36L, or 0.50L 4500psi Carbon Fiber Bottle in Gloss or Matte Black.
- Optional Barrel Band support to provide structural support for the Power Plant.
- Optional Barrel Band fitment available for Stock with OEM suppressor, Hajimoto Notos Modified, or FX Barrel configurations.
- Extremely stable externally adjustable regulator, Output 500psi~3600psi
- Provides over 130 shots.
- Ultra-stable output pressure
- Power Plenum with rotating joint for perfect clocking, locked in place with set screws.
- Standard 8mm quick disconnect male Foster fitting adapter for filling.
- Built-in Picatinny Rail Section for Bipod or Tripod Shooting.
- Power increase is achieved on the fly, but power decrease requires degassing the plenum/PCP.
While not 100% required, a barrel band is strongly recommended to carry the weight of the plenum, regulator, and cylinder assembly. This eliminates placing all of the lateral load on a small mechanical connection at the plenum-action interface.

5/8″-18UNF Threaded Unit
Flex Reg Hajimoto Configurations

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

Umarex Gauntlet Regulator Shim Pak
$18.50Select optionsHajimoto Productions Regulator Shim Kit For Umarex Gauntlet
I have put together a very easy and complete stainless steel shim kit so you can adjust your Gauntlets Regulator output. The shims that I have included give you a wide range of adjustability to mix and match different thicknesses to get the regulator to output exactly what you want. The shim kit comes with easy to follow instructions which guide you through the process as to what shims you need to add to typically achieve my recommendations for each Gauntlet Caliber.
The shim kit contains:
- 2 – #5 Shims.
- 1 – #3 Shim.
- 2 – #2 Shims.
(Two #2’s = One #4 | Two #5’s = One #10 | One #5 + One #3 = One #8, and so on)
To take a stock G1 .177/.22 from the stock 1100-1050PSI to my recommended 1350-1400PSI you would add two (2) #5 shims (10).
To take a stock G1 .25 from the stock 1900-1950PSI to my recommended 2100-2200PSI you would add one (1) #3 shim (3).
The included two #2 shims are for minor adjustments if you have a finicky regulator.DETAILED LESSON/EXAMPLE:
Let’s say your .22 Gauntlets regulator only puts out 1300PSI after installing the two #5’s when it should be 1350 to 1400PSI, you would add one #2 for a total of 12 to help get it there. If after the addition of the one #2, you’re still 50psi short so you would pull out the #2 and use the #3 for a total of 13.Always use a regulator output tester to confirm the output pressure of your regulator. It is the only safe and sure way to properly adjust the pressure of your regulator.
You have to fill and purge so the Belleville washers settle into the new preload. Be sure to slow fill your bottle the first time only to 500PSI and then purge it, fill slowly a second time to 1000, and then purge fill the final time slowly and watch to be sure the reg has settled and does not exceed your target pressure. If it does exceed your target pressure, stop filling, purge and shim less.
If you rapid fill, there is a good chance you will pop your burst disc.

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