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. Ninja X Reg Custom Output Regulator up to 3100psi

$144.95Select options
This is a genuine Ninja Paintball High Pressue X reg in 5/8″-18UNF thread that can be used on 3000PSI or 4500PSI.
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.

Installs on the Gauntlet 2 with minor tank shroud modifications, and the bottle shroud slides right over the carbon fiber cylinder.
The CF Tank is CE Certified and made to ISO 11119-3 standard. They have seamless aluminum alloy 6061 liner wound with high strength Japan-imported carbon fiber and glass fiber reinforced plastic full composite layers and subjected to an autofrettage pressure. This is a 22.5ci / 370cc carbon fiber 4500psi max fill cylinder.
The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I offer a tank shroud modification service for Gauntlet 1 owners that can be added to a build or provided as a mail-in service.
Please be careful if you have accessories on any of the M-Lok openings as the screws or MLok fasteners may protrude into the tank area and scratch the tank when the shroud is slid forward or back. We recommend that if you have any MLok accessories installed, you remove them when sliding the shroud on or off. We also recommend covering the brass inserts in the tank shroud with cloth tape to protect your carbon fiber finish.
