Pros: Better protection of the diode and lens from weather, mud, and bumps.

Trade-offs: Slightly smaller window and a bit more mass. Ideal for duty/rugged use.

Pros: Wide field of view, fast target acquisition, low weight. Trade-offs: Emitter is more exposed to rain/dust/impacts; use quality housings/covers.

Co-Witness Basics (Absolute vs. Lower 1/3)

Absolute co-witness: Iron sights sit in the middle of the optic window. Lower 1/3 co-witness: Irons appear in the lower third of the window; less visual clutter. Co-witness is influenced by mount/plat

Dot Size & MOA (Practical Picks)

2–3 MOA: Better for precision/range. 4–6 MOA: Faster for close-in targets and defensive use. Small dots favor precision; larger dots favor speed.
