Before using the MDO in snowy conditions creating significant glare, what component should be adjusted?

In snowy conditions where significant glare is present, adjusting the Anti-Reflection Device is crucial because it helps to reduce the reflection of light off the lens, which can be particularly problematic in bright, snowy environments. This device serves to minimize glare, allowing for clearer visibility and better targeting. By effectively managing reflections, the user can maintain focus and improve their overall effectiveness in aiming and observation. In such conditions, ensuring optimal visibility is essential for accurate performance, making the adjustment of the Anti-Reflection Device the most appropriate choice.
