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 with minor tank shroud modifications. (The Gauntlet 2 is shown to give an idea of what modification needs to happen and that is simply a hole drilled in the bottom of the plastic tank shroud for the fill nipple.

A 22ci aluminum 3000PSI cylinder with externally adjustable Ninja Flex Reg for your Umarex Gauntlet1! The volume of air in these 22ci tanks over the 13ci is mind-blowing!
The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I do offer a tank shroud modification service for Gauntlet 1 owners that can be added to a build or provided as a mail-in service.
The Gauntlet 2 forearm slide right over without any issue. Only one access hole needs to be drilled so the fill port is accessible at the bottom.
Consider picking up our extended foster fill adapter to make coupling and filling a breeze.
The Power Flex Combo allows the user to externally adjust the regulator output pressure on the fly with an adjustment range of 800PSI!
When installing the Flex 22 on the Umarex Gauntlet. Tighten the degassed tank and regulator assembly fully to the rifle, then back it off until the fill port is on the bottom and the gauges are left and right. Now fill the bottle with air and all will tighten up solid. Proper alignment will be achieved before the 360° maximum rotation limit is realized.
Comes with a dedicated Spanner Wrench for power adjustment. MADE IN THE USA!
Because of practical limitations, regulator output will be +/- 50PSI (3.5bar) within the requested output.
Part fits either the original Gauntlet or the Gauntlet 2
You must apply a liberal amount of silicone grease or other synthetic lube on the air strippers o-ring. Failure to do so will cause the o-ring to grip the dry interior of the shroud and cause damage to and break the air stripper. Please read the provided instructions.
Air Stripper comes with o-ring and silicone grease for installation.
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.
