The AN-M104 and M109 fuzes are identical except for three minor differences: The M109 has an additional spring- beneath the striker head, and a smaller striker disc: and its arming wire is removed from the arming pin when it is released from the plane. The AN-M104 arming wire is removed when parachute opens.

Since the fuze has a mushroom striker head and a sensitive firing pin, it is a semi-all-ways acting fuze and very sensitive if touched at any angle. If the mushroom head is flush with the fuze body and the delayed arming disc is out, then it is assumed that the fuze is in a fired condition and care should be taken not to lift the mushroom striker head away from the fuze body.

The AN-M104 has been replaced by the AN-M120A1.
