Ninja High Pressure Metric M18 Custom Output
$154.95 – $155.00
The Hajimoto M18*1.5 Thread can be used on 3000PSI bottles as well. Ninja Paintball is beginning to produce these with a polished brass bonnet. We will be forced to switch over to these polished brass version once all the black steel bonnets are gone.

This regulator is built with the ball/pin and spring removed so hot swapping will not be able to happen.

We do include the ball/pin and spring should you happen to have a thin pin depression system capable of actually opening the valve.

You should never try and unscrew a high-pressure output paintball-style regulator (anything over 1000psi output) 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.

Take advantage of a quality regulator for your high pressure application.

Flex Reg designed and configured specifically for RTI PCP’S such as Prophet, Priest, & Priest 2
This Flex Reg comes paired with a brand-new Carbon fiber 4500PSI tank. The regulator is externally adjustable and has an effective adjustable range of 900PSI (62bar).

Using the slider you select what the maximum output will be and because the regulator has the ability to adjust, you can reduce that maximum output pressure down as much as 900PSI (62bar). You can of course set the pressure anywhere along that 900PSI (62bar) range to suit your tuning requirements. The regulator will not have a pin or ball seal in the bonnet. The tank cannot be removed while under pressure and must be degassed.

Because of practical limitations, regulator max output will be +/- 50PSI (3.5bar) within the requested maximum output.

Comes with a spanner wrench for adjusting the output on the fly.

** This regulator is 5/8″-18UNF threaded and will not fit M18 threaded bottles. This configured Reg is not sold separately.
