CZ Evo 3 HB Industries Trigger spring kit

This 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 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.

• Provides 5.5lb Trigger Pull
• Fits all CZ Scorpion EVO 3 and 3+ Pistol and Carbine Models
• Includes (1) Trigger Spring, (1) Disconnector Spring, and (1) Firing Pin Safety Shim

Designed and Manufactured completely in USA.

Gunsmith Installation Recommended for All Parts.

*Please note that for 2016-2019 Scorpion S1 models (pistol/carbine) there was a high rate of welded trigger packs. The retaining weld should be identified and removed prior to any trigger pack work.
