The HB Industries spring kit provides a 5.5lb trigger pull (down from 9.0+ lbs factory trigger) for the CZ Scorpion EVO3 carbine rifle or pistol models. Simply remove your factory trigger and disconnector springs (#63 and #50 respectively on the factory parts diagram) and replace them with our application specific trigger and disconnector springs. Both springs in our kit must be used together. Gunsmith installation is recommended, but not required.
TIP: Many customers opt to also deburr and polish the working surfaces of the trigger components while replacing these springs; doing so will typically result in an even lower trigger pull weight and smoother trigger operation.
