This FX Impact MKII Tuning Regulator by Huma-Air is specially designed as a "one on one" replacement regulator for your FX Impact MKII.


Unfortunately the fixed limited space in the FX Impact MKII action was not sufficient for our standard Huma-Air Regulator design, so we had to comply our design to the ratio's used by FX.
Never the less we have accomplished to make a great replacement regulator what will solve the know issues of the factory regulator.
This regulator is a replacement for FX regulators with 10 mm belleville springs.

So what can you expect of the Huma-Air FX Impact or FX Crown Tuning Regulator:

The output performance of the Huma-Air Impact MKII regulator won't be very different compared to a good functioning FX factory regulator, but we have some other benefits available
Three special pressure ranges are available so you can tune the rifle exactly according to your own wishes
This Huma-Air FX impact  regulator can be adjusted higher in pressure from the outside while the rifle is under pressure.
By using another type of material for the valve and piston, there is no way you can damage the piston because of faulty pressure adjustments.
We also supply some extra valves, so in case you adjust the pressure to the wrong side, and you damage the valve, it can be replaced without any extra costs.


Pressure settings

The design of the regulator makes it posible for setting it exactly to your wishes while placed in you FX impact MKII by watching the output pressure gauge on you rifle.

We have currently three pressure ranges for the FX Impact or FX Crown Gen3 regulator available:

- The High Pressure range, 100-165 Bar, what will suit all calibers within the normal FAC range.
- The Extra High Pressure range, 145-190 Bar for more extreme purposes and very good for the slugs and heavy pellets
- A low pressure ranges what will suit the sub 12 ft/lbs versions perfetly
Please note: you need to do the stacking of the belleville springs on the piston yourself according to the manual, because we do not want to risk them to fall off the piston during shipping.

When you order your FX Impact  MKII regulator you will receive:

  • Your regulator with the belleville springs, matching the pressure range you choose.
  • A set of spare valve disks
  • We will also include a “Huma-Air regulated” breech sticker
  • Fitting instruction as pdf download


Huma-Air Quality Control


Huma-Air regulator's are CNC produced out of high grade aircraft Aluminum and bronze.
To guarantee a perfect product, every regulator is manually assembled, tested and adjusted to the requested pressure. 
We only use high-end materials and our belleville springs are designed for critical applications to achieve the highest repeat accuracy.

I’ve had a Huma regulator on my BSA R10 for about four years without a hint of a problem. Always returns excellent results., so when I bought an FX Impact Mk2 in FAC I naturally fitted one to that too. The consistency is amazing and has made an already extremely accurate rifle just that bit better. Easy to fit following the instructions and YouTube videos and so simple to set up correctly. Money well spent, again.

Super Hiper FX Impact MK II is number one :-)

Very well documented how to install, extremely stable

This is an excellent, dependable regulator. Fitting and adjusting is easy, although i would say the trigger group certainly needs removing for accurate adjustment

The only criticism I have, is why do they use a slot for a flat heat screwdriver on the adjuster screw? This causes more problems than using the fx original hex key for pressure adjustment..

I have owned and used extensively a multitude of air rifles over the years (all FAC / High power) from Daystate to FX. Following significant testing, tuning and thousands of rounds shot, I have yet to find a regulator that outperforms Huma! Huma simply make the most reliable and consistent regulators for PCP air rifles. All my PCP air rifles have Huma regulators fitted. Even brand new rifles instantly have a Huma regulator installed. Simply put, Huma regulators are industry leading. The build quality combined with the stability, consistency and reliability enable elite shooters to tune and have there rifles perform at the highest possible level. I could not recommend nor complement Huma regulators enough.

Excellent service and help

Very nice regulator, in my case, works better/more stable, than the original from fx.
However, Id rather see a hex screw instead of the philips flat, because its easier to adjust the regulator with an allen key.

ordered the Huma regulator for the impact mk11, it arrived about a week ago from Holland,assembled it and fitted in about 35 minutes,tested it and about 30 shots it had settled,I am well pleased with it.Thanks Huma.

This regulator works just a Huma advertise. The Impact MK2 reg in my particular sub 12 ft/lb rifle had a tendency to creep up when not in use causing the first couple of shots to be way off, took quite a few seconds between shots to stabilise and most annoyingly had would settle between 45 to 55 bar and FPS spread was 30 to 40fps with sorted jsb pellets. The factory item was stripped and reinstalled twice but with no improvements. The Huma reg took just 20 or 30 shots to settle and seems absolutely bullet proof. Pellet speed spread is now maximum 9 FPS over 20 shots.
