Key Features
Optical Performance
- Variable Magnification: Features a versatile 12-40x magnification range, allowing for broad area scanning at lower power and detailed target resolution at higher magnifications. This range supports effective target identification and engagement verification across various distances.
- 60mm Objective Lens: The 60mm objective lens optimizes light gathering capability, enhancing image brightness and resolution, particularly beneficial in low-light conditions or when resolving fine details at extreme ranges.
- Proprietary Lens Coatings: Equipped with full multi-coatings on all air-to-glass surfaces to maximize light transmission, mitigate glare, and ensure superior image fidelity and contrast across the entire magnification spectrum. This optical design delivers a flat, clear image with accurate color rendition.
TMR MK4 Reticle Integration
- First Focal Plane (FFP) TMR MK4 Reticle: The integrated Tactical Milling Reticle (TMR) MK4, positioned in the first focal plane, ensures that reticle subtensions remain accurate at all magnification settings. This milliradian-based reticle facilitates precise range estimation, holdovers, and windage corrections, enabling rapid adjustments for follow-up shots or ballistic data confirmation.
- Data Overlay Capability: The TMR MK4 provides distinct reference points for measuring target dimensions and calculating bullet impact shifts, a critical asset for precision marksmanship.
Construction and Reliability
- Rugged Chassis Design: Constructed from a high-strength aluminum alloy, the chassis provides a durable and stable platform for the optical system, capable of enduring rigorous field use.
- Environmental Sealing: Internally purged with a proprietary inert gas blend and completely sealed to ensure waterproof and fogproof performance. This prevents internal moisture accumulation and maintains optical clarity across extreme temperature fluctuations and challenging weather environments.
- Protective Armor: The exterior is designed with protective elements to absorb impacts and enhance grip, mitigating damage from incidental contact.
Ergonomics and Integration
- Smooth Focus Mechanism: Features a precise, tactile focus knob that allows for fine-tuning of image clarity, critical for accurate target resolution.
- Mounting Adaptability: Designed with standard mounting provisions for secure attachment to tripods and other support systems, ensuring stable observation platforms.
