Huma FX Impact Tuning Hammer Spring - High Power Rifle Scopes 5mm For Right-Hand RiflePower tuning Hammer spring for your FX Impact MKI or MKII 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.
