HBI CZ Scorpion EVO 3 S1 Reduced Weight Trigger Spring Kit
Out Of Stock!
We will notify you when this product becomes available.
The HBI 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 CZ Scorpion EVO3 Pistol and Carbine
- Includes (1) Trigger Spring and (1) Disconnector Spring
Designed and Manufactured completely in USA.
Gunsmith Installation Recommended for All Parts.
*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. For more information on removing the weld please see our info here: Scorpion Trigger Pack Weld
