OVERVIEW
Key Advantages and Product Features
Ultra-High 5-30X Magnification Range
The 5-30X magnification range provides exceptional capability for extreme long-range shooting.
The lower magnification allows practical field observation, while the 30X setting provides detailed target analysis and precision aiming for demanding shooting scenarios.
Large 50mm Objective Lens
The 50mm objective lens improves light collection capability and supports a brighter, clearer sight picture.
This configuration helps maintain optical performance during changing outdoor lighting conditions.
Side Focus Parallax Adjustment
The side focus system allows shooters to adjust focus from close distances to infinity.
This helps reduce parallax error and improves aiming consistency during long-range shooting.
Mechanical Illuminated Reticle
The mechanical illumination system provides reliable reticle visibility without relying on complex electronic controls.
The special reticle platform can be customized for different precision shooting and hunting requirements.
MIL Precision Adjustment System
The ±12MIL elevation and windage adjustment range with 1/10MIL click value provides accurate correction capability.
This supports shooters who use ballistic calculations and precision shooting methods.
Push-Pull Self-Locking System
The locking mechanism helps prevent accidental turret movement during transportation and field use.
This improves reliability for professional shooters and outdoor enthusiasts.
Durable One-Piece Tube Construction
The 30mm one-piece tube design provides excellent structural stability and durability.
Combined with shock resistance and nitrogen-filled fogproof protection, the scope is designed for demanding shooting environments.
High Transmission Optical Performance
The broadband multi-coated optical system improves brightness and image clarity.
The high single-surface transmission performance helps provide a clearer sight picture for long-range observation.
