Trigger Arming Handle

5-18. The trigger arming handle is located forward of the trigger bar and has two positions: SAFE and ARM. Leave the trigger arming handle on SAFE until the launcher is in the correct firing position (Figure 5-9). To press the trigger, you must first pull the arming handle forward and lock it in the ARM position.

Trigger Assembly

Firing Pin Rod Assembly

5-20. The rear sight cover and the firing pin housing are on the top rear of the inner tube. Inside the housing, the primer and the firing pin rod are aligned (Figure 5-10). Pressing the trigger bar releases the tension on the firing pin rod assembly, allowing the firing pin to strike the center of the primer.
