Which of the following is NOT among the three common sight systems described?

• A. Iron sights
• B. Red dot sight
• C. Holographic or magnified optic
• D. Laser sight

Answer: (D)

Laser sights are an aiming aid that projects a beam to indicate where you are aiming, but they don’t provide a true reticle or a magnified aiming image like the other common sight systems do. The three standard sight systems described are mechanical iron sights (front and rear alignment), red dot sights (a simple illuminated reticle for quick aiming), and holographic or magnified optics (reticle or image with magnification for precision). Because the laser doesn’t fit into that reticle, magnification, or mechanical alignment framework, it isn’t counted among the three typical sight systems. So this option isn’t part of the described trio.
