The standout feature here is the massive 25mm objective lens, which gives you an expansive field of view, making it easier to stay aware of your surroundings.
Durability is where the MRO really shines. It’s constructed from 7075-T6 aluminum and is fully sealed and waterproof up to 100 feet. The battery life is impressive too—up to 5 years on setting 5.

This makes it easier to track moving targets—perfect for competitive or dynamic shooting scenarios.
