Medusa trigger in APG magizine

[Army]

There are "pull" magnets at the top of the trigger, ala Emag. And you can see the one at the bottom. The top ones hold the trigger up and away from the sensor switch, the bottom ones repulse each other, theoretically "bouncing" the trigger. This results in a stacking trigger pull.

the trigger would not stay pulled on an automag, the valve would push it back

my, it looks like APG spilled about an ounce of House of Color "Ugly as sin #5" on one of their master copies.
