HKP/H&K MP5 9mm Semi-Auto SEF Single Stage Trigger Pack
This trigger pack starts as a factory F/A trigger pack before being converted into a semi-auto trigger pack and receiving single-stage trigger work. This is the best option for users who want a smooth, single-stage, genuine trigger pack instead of modifying the trigger pack with aftermarket triggers and hammer systems.
Compatible With:
- HK MP5/MP5K
- HK SP5/SP5K (SEF Housings)
- Zenith, PTR, and Century Arms – Full size and K variant
- Any in-spec. MP5, MP5K clone
- This will work on 93 and 91 variants by swapping out the ejector lever and hammer spring to the correct caliber.
