Important Before You Begin
This video is provided as a general installation overview for WHA customers. MP5-pattern firearms can vary by manufacturer, model, pin/shelf pattern, tolerance, and configuration. If you are unsure whether your setup is correct, stop and contact War Hammer Armaments before proceeding.
- Confirm your host firearm manufacturer and model.
- Confirm full-size MP5 or MP5K pattern.
- Confirm pin or shelf pattern.
- Confirm all required Super Safety components are present.
- Use qualified gunsmith or armorer support if installation or fitment is unclear.
- Do not continue use if fitment, reset, cycling, or wear appears abnormal.
Important Notes
Do not dry fire the lower while it is not attached to the firearm/upper receiver. Dry firing the lower by itself can cause the front of the polymer lower/receiver to crack or break.
When installed on the firearm, the Super Safety system may not reset during dry-fire function checks. Live fire is typically required for the system to reset and function as intended.
Installation and handling instructions are included in the package when shipped.
