The Trijicon Tenmile 5-50×56 rifle scope is a precision optic specifically engineered for extreme long-range applications and competitive shooting disciplines. Designed for the discerning operator, this optic integrates advanced optical performance with robust mechanical integrity, providing precise engagement capability out to distances previously unattainable without dedicated spotter assistance.
Key Features
Optical Performance
The Tenmile 5-50×56 features a 56mm objective lens paired with premium, fully multi-coated glass elements, optimizing light transmission across the entire magnification range. This optical configuration ensures exceptional image clarity, accurate color rendition, and high contrast, even in challenging light conditions. The broad 5-50x magnification range provides granular target resolution required for precise shot placement at extended distances, while maintaining a sufficiently wide field of view at lower magnifications for situational awareness.
Precision Adjustments
Equipped with a 34mm main tube, this optic facilitates a generous range of internal elevation and windage adjustment, critical for ballistic compensation at extreme ranges. The MRAD-based turrets offer crisp, tactile, and audible clicks at 0.1 MRAD increments, ensuring repeatable and accurate tracking. A reliable zero stop mechanism is integrated to prevent over-rotation, allowing for rapid and confident return to zero. Parallax adjustment is managed via a dedicated side focus knob, permitting fine-tuning for a sharp image from 10 yards to infinity, mitigating potential aiming errors.
MRAD Cdot Reticle System
The Second Focal Plane (SFP) MRAD Cdot reticle provides precise holdover and windage corrections without obscuring the target, critical at high magnifications. Its design is uncluttered, presenting a clear sight picture while offering essential reference points for ranging and shot correction. The illuminated center dot enhances target acquisition in low-light environments, with multiple brightness settings for optimal visibility against varied backgrounds.
Rugged Construction
Constructed from aircraft-grade aluminum, the Tenmile 5-50×56 chassis is engineered for durability and reliability under austere field conditions. The optic is nitrogen-purged and O-ring sealed, ensuring waterproof and fogproof performance across a wide range of environmental temperatures and humidity levels. This robust design guarantees consistent performance and maintains zero integrity despite significant recoil or harsh handling.
