HK MP5 Trigger Pack – Single Stage Semi-Auto – SEF

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.
