*Please note that for 2016 Scorpion S1 models (pistol/carbine) there is a high rate of welded trigger packs. The retaining weld should be identified and removed prior to any trigger pack work.
HBI’s spring kit provides a 5.5lb trigger pull (down from 9.0+ lbs factory trigger). Simply remove your factory trigger and disconnector springs (#63 and #50 respectively on the factory parts diagram) and replace them with HBI’s application-specific trigger and disconnector springs. Both springs in our kit must be used together. Gunsmith installation is recommended.
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.
