FX Impact Power Tuning Hammer- and Valve Return Spring

Power Tuning Hammer Spring + Valve Return Spring Set For Your FX Impact With Power Plenum 

This is a set of 2 power tuning springs for your FX Impact with Power Plenum and it consists of:

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 powercurve 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 hybride slugs.


1x FX Impact Power Tune Hammerspring

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
