FX Impact MKI-MKII First Stage Tuning Regulator by Huma-Air

Huma-Air External First Stage Tuning Regulator For The FX Impact MKI and MKII

This First Stage Tuning Regulator built by Huma-Air allows you to convert your FX Impact MKI or MKII into a Dual Stage regulator system similair to the current FX Impact M3 regulator system that is described by FX as below:

“The first regulator pre-reduces the pressure in preparation for the second regulator. This provides less stress on the second regulator and achieves a more constant output pressure with less standard deviations. Advised is to use about 30-40 BAR difference between the 1st & 2nd regulator.”
The dual stage regulator will function as the first stage regulator.

It is equipped with a 23 mm 250 Bar pressure gauge with white dial as standard; this gauge will indicate the fill pressure of the bottle. Optionally you can select different pressure gauges in terms of pressure, diameter and color, with or without black tactical cover. The gauge can be aligned stepless into it’s position so it always looks good on your rifle.

Available gauges:

• 23 mm, 250 bar gauge with white dial (standard)
• 23 mm, 250 bar gauge with white dial + black tactical cover
• 23 mm, 250 bar gauge with black dial
• 23 mm, 250 bar gauge with black dial + black tactical cover
• 23 mm, 300 bar gauge with white dial
• 28 mm, 315 bar Wika gauge with black dial
• 28 mm, 315 bar Wika gauge with black dial + black tactical cover

The original foster male quick connect coupler of the rifle will be replaced by an included blind plug and the foster male fill coupler from your impact will be re-used in the regulator. The position of the gauge and and foster can be chosen left or right.
When the regulator is fitted to the rifle you can read the primary fill pressure of the bottle on the regulator’s pressure gauge. The first stage regulator output pressure can be read on the factory gauge (previously used as fill pressure gauge) and the second regulator output pressure can be read on the original FX regulator pressure gauge.

Pressure can be set by turning the set-screw of the regulator, which can be found inside the regulator, half a turn counter clockwise equals about 25-30 bar pressure increase. The set pressure can also be read on the rifle’s pressure gauge.
This first Stage Tuning Regulator will be screwed in between the pressure bottle and the action of the FX Impact. The pressure bottle can be screwed on- or off the rifle without depressurizing the rifle.
The first stage regulator will ad only 31 mm of length. Please check if it does not interfere if you use a 580 CC bottle or larger after market silencer.

The regulator can be fitted easily with no modifictions to the rifle. You just need to unscrew the FX bottle connector out of the action and replace it with the regulator.

The benefits of this Huma-Air First Stage Tuning Regulator for your FX Impact MKI or MKII:

• Higher accuracy due to the elimination of the pelletspeed fluctuations
• High refill speed
• The second regulator will work smoother, due to the constant input pressure
• The position of the foster and pressure gauge can be turned around for 180 degrees. So you can align it to your own wishes.
• Under the pressure gauge there is an o-ring that makes it possible to line the dialplate up straight for the eye.
• Fitting instruction available as pdf download
