Power Tuning Hammer spring for your FX Impact MKI or MKII

 

This hammerspring has a bit more higher powercurve compared to the MKI hammerspring what will give you more flexibility and power adjustment options when using the powerwheel of your FX Impact.
It's great when you want to tune your FX impact for slugs or hybride slugs and we prefer to use this spring over the factory spring when you use the powerplenum in the MKII


Also it makes a perfect combination with our FX Impact Tuning Valve Return Spring

Excellent product, loads of slack on hammer adjustment still easily shooting over 900fps on min with jsb mk2 .25cal 150bar saving air that I couldn't do with factory spring! Thanks guys!

Another well thought out quality upgrade to my FX Impact. HUMA lead the way in perfection.

Great quality products 👍

I bought this spring to replace the standard spring in my .25 FX Crown as I have fitted a 8.5gram hammer weight & Huma extra high pressure regulator & 6.35mm valve seat.
The Huma spring is exceptional quality & postage to 13 days delivered to my door in Australia.
Exceptional team at HUMA.
You should all be very proud to work for such a company.
I hope they look at making the same power spring &
valve stem they have made for the FX IMPACT for the FX CROWN.
FINGERS CROSSED IT WILL HAPPEN

Werkt prima, samen met de dualflow tf poort en de pin probe heb ik de regulator druk van 135 bar terug naar 105 bar kunnen zetten zonder veel snelheid te verliezen

Very good product that Huma gave to thank you

Wow....almost to much power, after changing the PP stock hammerspring out with the Huma one! almost to much power 😁 perhaps I would need to get the rubber ball for the valve adjuster spring, to reduce power when just plinking in the backyard. One will need to re adjust the hammerspring, reg pressure and valve adjuster/stop. Basically recalibrate the gun, and finding the sweetspot/hamronics again.

Upgrade over the one that FX supply with the Power Plenum Kit - this is needed for the higher reg pressures and f/sec results.

Perfect for increase the speed of FX impact.
This spring+huma regulator +hi flow transfer fort and pellet probe
50grains at 1017 fps. Nice

It´s amazing so much more power a simple spring can produce! on the other hand, Huma always finds new ways of pressing the limits!
Always quick delivery and the best support!
Huma Rocks!

Yes love this fits well for my gun and come very fast

Francisco - 21-09-2020 11:40


Excellent, it took a while to arrive, due to the pandemic situation we are in ... I haven't installed the spring yet. I hope it will increase the speed ....

Works fine to make a .25 cal Dreamline Classic PP to shoot NSA 27 gr at 980fps, at 125 bar reg with not totally maxed capacities sub MOA at 65 yards.
Nice little tool that really works well in the Dreamline .25 for 25 full power shots. Original spring in the same setup ranged for a max speed of 955fps.
