The Timney Replacement Trigger for HK Roller-Delayed Rifles (Timney part number MP5) is a black, curved, two-stage trigger built for HK91, HK93, and HK94 semi-automatic variants, with a 4-pound pull. The housing is 6061 T6 aluminum, anodized black for weather and corrosion resistance, while the hammer is S7 tool steel, heat treated and NP3 coated for lasting lubricity. The trigger shoe and disconnector are machined from billet A2 tool steel, heat treated, and carbo-nitride coated for a smooth, durable action. It reuses your rifle’s existing ejector lever, spring, and axis pin matched to your chambering, and it installs without a gunsmith.
