- Kit Includes:
- 1x 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.
- 1x FX Impact Power Tune Hammer spring: This hammer spring has a bit more higher power curve compared to the MKI hammer spring what will give you more flexibility and power adjustment options when using the power wheel of your FX Impact.
- 1x 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 gram. Our set contains 2 weights; 1 x 6,9 gram and a 8,5 gram so you can setup your rifle exactly to your own wishes.
- High Flow Pin Probe: For maximum airflow in your FX Impact.
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.
Available in .22, .25 and .30. For the .35 we have a separate kit available here
