Power Tuning Hammer Spring for your FX Air Rifle
Suitable for the FX Impact 1/2/3/4, Crown, Dreamline, Maverick, Wildcat, DRS, Panthera, Dynamic and King
This hammer spring 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
