FX Impact Lighter Valve Return Spring
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 hybrid slugs.
Note: Colour of the spring may vary from what is shown in pic.
Contact us if you need any customization and we shall be happy to get it done for you.
