Fits Notos / HajiNotos
The Umarex Notos was designed to be flexible to your shooting needs. The Notos has plenty of accessory rail on the top side of the rifle allowing shooters to install the optic of their choice or, a set of fixed sights. The high-contrast Fiber Optic elements pick up plenty of available light for quick accurate shooting in all lighting conditions. These Fiber Optic sights can be installed in just minutes.

Barrel Service Notos/Notos G2
Notos/Notos G2 Barrel Service
This is what we do to our Haji-Notos/Notos G2 Custom Builds. but you can have the same service performed on your Notos/Notos G2 barrel as well. The Transfer port work increases the port and polishes the opening to allow greater airflow to produce more power more efficiently.Â
Notos G2 Important note: The barrel conversion will not allow you to use your stock pressure tube. You will need to bottle convert your Notos G2.
You ship us your Notos/Notos G2 Barrel and we execute the following:
Notos Barrel Removal
Your Barrel is very easily removed by removing the 2.5mm button head screw on top of the Picatinny rail near the magazine opening. Once the 2.5mm screw is removed, there is a 2mm set screw below (or 2 2.5mm screws for the Notos G2) it that holds the barrel into the receiver block. Loosen the 2mm screw four revolutions and slide out the barrel.
Shipping
When you place the order for the above-described service, we will 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 and service order number required for you to ship us your barrel for modification.
Haji-Notos Mag 11 rounds
This is an expanded magazine for the Umarex Notos PCP. The magazine is a brand-new design that loads from the right and employs a removable magnetic lid for easy loading. Allow for a smooth and consistent chambering of rounds without issue.
Please note that our design loads from the right.
Be sure to install and remove the mag at least 10 times before using it so that it breaks into your mag well.
The Haji-Notos magazine is compatible with a red-dot or optic, but it does not work with Umarex fixed fiber optic sights. Please note that the actual finish may differ from that shown in the photos.
LOADING THE NOTOS MAGAZINE
THIS IS AN AIRGUN ONLY PART

This part is designed and manufactured by DonnyFL
Remember to always order your suppressor one size larger for shrouded barrel PCP’s.
If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.
The .177/.22 is for shrouded barrel .177 or direct barrel threaded PCP’s in .22.
The .22/.25 is for shrouded barrel .22 or direct barrel threaded PCP’s in .25.
The .25/.30 is for shrouded barrel .25 or direct barrel threaded PCP’s in .30. The exception to this rule is the Gauntlet .30 which is shrouded but because of the unique end cap, marries the barrel and shroud at the end.
The Tanto, Tatsu, FX, or Sumo are not recommended for the Gauntlet .30 caliber because of the relatively small internal volume of these suppressors and the elevated operating pressures of the G30. We recommend the Ronin be used on all of our G30 Builds.

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.
