Which component is described as showing the actual gun position by providing angular measurements to the Gun Control Panel?

• A. Base Plate
• B. Bolt & Carrier
• C. Forward/Aft Feed Gates
• D. Optical Encoder

Answer: (D)

Position feedback is essential for the Gun Control Panel to know the actual gun angle. An optical encoder serves as the angular position sensor. As the gun rotates, a patterned disc interrupts light to a photodetector, producing pulses that represent increments of rotation. The control panel interprets these pulses to determine the exact angular position in real time, providing true gun alignment data. The other components are mechanical elements: the base plate is the mounting surface, the bolt and carrier cycle the action, and the feed gates handle ammunition; none of them produce or convey angular position information to the panel. Therefore, the component that shows the actual gun position by providing angular measurements is the optical encoder.
