Spark Hair Trigger Spring Set by AIRSOFT97

Spark presents the first dedicated trigger response upgrade components engineered with premium piano wire composition and dual variable tension ratings—100% Made in Japan. The advanced steel composite delivers exceptional mechanical spring retention, reduced operational resistance, and superior responsiveness through high-precision tempering processes. The coil configuration is manufactured using high-precision winding technology, ensuring perfect trigger return and dimensional precision equivalent to custom factory target components. The specialized tension ratings minimize trigger pull weight to decrease shooter finger fatigue while significantly reducing target engagement split times during rapid semi-automatic fire. Standardized mechanical dimensions and strict compliance criteria eliminate conventional component resistance and maintain consistent trigger reset positioning for extended gearbox reliability
