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 – 900 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.

Ninja Paintball is beginning to produce these with a polished brass bonnet. We will be forced to only offer the polished brass version once all the black steel bonnets are gone.
We do include the ball/pin and spring should you happen to have a thin pin depression system capable of actually opening the valve. The only function of this pin/ball is to allow the tank to retain air if it is off of the PCP. This is a paintball thing and should not be used in in HPA.
You should never try to unscrew a high-pressure output paintball-style regulator while it is under pressure. You will destroy the threads as they are not designed to be threaded on and off under load. Degas and then remove the regulator and bottle. Read more in the following article https://hajimotoproductions.com/index.php/2024/11/11/regulator-thread-damage/
The ball and spring are provided but removed from the regulator.
