Contains cocked striker.
The Release Firing Device M5 is a mechanical device designed for firing charges by the removal of a restraining load from the device. A load of at least five pounds is required. When the load is removed, a spring loaded striker swings over to detonate the percussion cap.
The parts are a rectangular metal body and release plate, a striker and spring, a safety pin, and a standard nipple base. The release plate, when held down by the safety pin or by a weight, prevents the striker from swinging over to detonate the percussion cap.
When the device is set with a weight on top and the safety pin removed, it is in an armed condition. If the restraining weight is removed, the release plate is forced up by the striker as it swings over to detonate the percussion cap.
No information about hazardous components.
