1. An ammunition counting device, comprising:
an ammunition guide for accepting ammunition rounds;
two sensors disposed along a path that the ammunition rounds travel through the ammunition guide, each sensor for producing a sensor signal upon detecting presence of an ammunition round;
an electronics assembly for receiving sensor signals and producing a count signal responsive thereto, wherein a direction of travel of the ammunition rounds through the ammunition guide is responsive to a sequence of sensor signals from the two sensors such that an ammunition round passing in a first direction produces a count signal representing a count of plus one and an ammunition round passing in a second direction opposite to the first direction produces a count signal representing a count of minus one, wherein the ammunition count is responsive to the count signals;
a display responsive to the electronics assembly for displaying the ammunition count;
a fixture plate attached to the ammunition guide, wherein the ammunition rounds pass below the fixture plate;
a pin for passing through spaced-apart pin horns affixed to an upper surface of the fixture plate proximate a first edge of the fixture plate;
the fixture plate further comprising a projection extending from the upper surface proximate a second edge of the fixture plate, the projection defining an opening or slot therein, the second edge opposite the first edge;
the electronics assembly further comprising a shoe disposed on a first surface thereof, the shoe for mating with the opening or slot; and
the pin exerting a force on a second surface of the electronics assembly for retaining the shoe within the opening or slot, the second surface opposite the first surface.
