OVERVIEW
Key Advantages and Product Features
Versatile 4-24X Magnification Range
The 4-24X magnification range provides an excellent balance between practical shooting and long-range precision.
The lower magnification supports target acquisition and field observation, while the higher magnification enables detailed target analysis at extended distances.
Large 56mm Objective Lens
The 56mm objective lens improves light collection capability and supports a brighter, clearer sight picture.
This configuration is ideal for shooters who require strong optical performance during long-range shooting and changing lighting conditions.
Mechanical Illuminated Special Reticle
The mechanical illumination system provides reliable reticle visibility without relying on complex electronic controls.
The special reticle design can be customized for different shooting applications, including hunting, competition, and precision shooting.
Side Focus Parallax Adjustment
The side focus system allows adjustment from 10 yards to infinity.
This helps reduce parallax error and improves aiming consistency during precision shooting.
Precision 1/4MOA Adjustment System
The ±40MOA elevation and windage adjustment range with 1/4MOA click value provides accurate correction capability.
This allows shooters to make precise adjustments during zeroing and long-range shooting.
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.
