Pellet power tune kit for your FX Impact by Huma-Air.
Get the maximum performance out of your FX Impact when using pellets. (Also compatible with slugs)
On special request from our customers, we made this Pellet power tune kit for the FX Impact.
This power tune kit consists of the items below to get maximum performance out of your FX Impact.
High Flow Pellet Probe for maximum air flow through the transfer port.
Power Tuning Hammer and Valve Return Spring Set
High Flow Dual Hole Transfer Port
Valve Return Spring
This slightly weaker valve return spring can be used on any FX Impact equipped with the genuine FX Power Plenum.
This spring has a bit weaker power curve compared to the original valve return spring what will result in a bit longer valve opening time to get some more extra power out of your rifle.
It's great when you want to tune your FX impact for slugs or hybrid slugs.
FX Impact Power Tune Hammer Spring
This hammer spring has a bit higher power curve compared to the factory used hammer spring what will give you more flexibility and power adjustment options when using the power wheel of your FX Impact.
It's great when you want to tune your FX Impact for slugs or hybrid slugs, and we prefer to use this spring over the factory spring when you use the power plenum in the MKII.
NBR Buffer Ball
The rubber buffer ball is placed inside the spring and limits the stroke length of the valve.
FX Impact Hammer Weight Tuning Set
This set of two different sizes of hammer weights for your FX Impact are perfect if you want to do a power tune.
The standard hammer weight FX uses is about 6 grams.
Our set contains 2 weights:
You can setup your rifle exactly to your own wishes.
They are compatible with the FX Impact MKI, MKII and M3.
Note: Any modification done to the airflow of your rifle, will affect the entire setup and performance, you might need to re-adjust the settings of your rifle again to get the best possible performance.
Important Note: Compatible with M3 factory screw which locks the bolt in place.
If you need the bolt for compatibility with M4 factory screw, do specify in the comments when you place the order.
