Expert Binocular Group

The Steiner Optics 10x50 Military M1050r (SUMR) Binoculars is a rugged, military-grade optical instrument designed for professional observation in demanding environments. Engineered to strict military specifications, this binocular delivers exceptional clarity, durability, and precision for tactical operations, surveillance, hunting, and long-range observation.

Featuring 10× magnification and large 50 mm objective lenses, the M1050r provides bright, high-contrast images even in low-light conditions such as dawn, dusk, or fog. Its integrated SUMR (Steiner Universal Mil Ranging) reticle allows users to estimate distance and target size accurately, making it particularly valuable for tactical and field applications.

The binocular uses fully multi-coated optics and Porro prism design to maximize light transmission and depth perception, ensuring sharp images with natural color fidelity. Built with a tough Makrolon® polycarbonate housing and NBR rubber armoring, it withstands harsh impacts, extreme weather, and rough handling. Nitrogen-filled construction keeps the optics fog-free and waterproof, making it reliable from arctic cold to desert heat.

This bundle also includes protective caps and a microfiber lens cloth pouch, helping keep the lenses clean and protected during transport and storage.
