FX Hammer Spring Adjuster – Genuine FX Airguns Spare
S83304
The FX Hammer Spring Adjuster is a genuine FX Airguns factory spare that controls the preload — and therefore the tension — applied to the hammer spring in an FX PCP air rifle. By threading the adjuster in or out, the shooter can increase or decrease the force with which the hammer strikes the valve, directly influencing muzzle velocity and the efficiency of the air charge. This makes it a key component both for routine service and for power-curve tuning: a worn or damaged adjuster will produce inconsistent preload and erratic shot-to-shot power. Replacing the adjuster with a genuine FX part restores precise, repeatable spring tension adjustment. It is designed to work in conjunction with the FX hammer spring assembly and should be fitted by anyone comfortable with FX PCP strip-down procedures.
