Figure 9. Launcher Assembly Cutaway Drawing.
Figure 9 shows the mechanical firing mechanism in the
Firing Assembly. When the cocking handle is pulled down,
the firing pin is pulled back from the firing chamber and the
firing pin spring, part of the firing assembly, is
compressed. The spring-loaded lever arm falls into a
keyway in the firing pin and firing assembly. You will hear
a distinct click when the lever arm falls into the keyway,
releasing the firing pin. The firing pin initiates the .22
caliber blank cartridge, launching the bumper.
