FX DRS Tuning Hammer Spring

The FX DRS Tuning Hammer Spring delivers a noticeably higher power curve than the factory spring, providing greater flexibility for power adjustments. Its design is optimised for use with hybrid slugs, ensuring reliable performance in demanding setups. When paired with a power plenum or slug power kit, this spring maximises the output of your FX DRS system. Constructed from high‑tensile spring steel, it offers durability and consistent spring tension over time. The spring’s increased stiffness enables finer tuning across a broader range of air pressures. It integrates seamlessly into existing FX DRS assemblies without modification. Users report improved shot consistency and enhanced muzzle velocity after installation. The spring is lightweight, contributing minimally to overall system weight. Its compact form factor fits within the standard FX DRS housing. This upgrade is ideal for enthusiasts seeking superior control and power in their airsoft rifles.
