Aircraft Grade T6063
Aircraft-grade T6063 aluminum, single-piece construction with anodized finish for extreme durability.Etched illuminated glass reticle,IPX7 waterproof rating,Nitrogen-filled for fog resistance 5 year warranty
Fog Resistant
The Keck rifle scope uses nitrogen purging technology to prevent internal fogging. By filling the scope with nitrogen, moisture in the air is displaced, preventing internal fog formation due to temperature changes. This design ensures a clear view in various environmental conditions, enhancing shooting accuracy and reliability.
Shock Resistant
At 100 yards, after 2500 rounds of 7.62x51mm live fire, the deviation was less than 2 MOA with no noticeable shift in the aiming point. Despite the strong recoil, the lenses and internal optical components remained intact, with no damage or displacement, and the optical clarity and brightness were unaffected. The external protection and internal mounting systems showed no loosening or damage, ensuring long-term aiming stability.
Water Resistant
Keck scope features IPX7 waterproof protection, allowing it to be submerged in water up to 1 meter deep for up to 30 minutes without damage. This level of protection ensures reliable performance in harsh weather or humid environments, meeting the demands of outdoor use.
Keck Reticle and Turret Accuracy
The turret accuracy of this scope reaches up to 99%, ensuring precise adjustments with each click. This high-precision design allows users to calibrate their aim more accurately, enhancing shooting reliability and accuracy, especially in long-range shooting scenarios.
Anti-Reflective Lenses
Enhancing Light Transmission: Effectively reduces light loss on the lens surface, allowing more light to enter the scope, thereby improving image brightness. Reducing Glare and Reflection: In strong or backlit conditions, reflections on the lens surface may interfere with observation. Anti-reflective coating significantly reduces such reflections, preventing interference with aiming. Improving Image Quality: By minimizing reflected light and internal light scattering, anti-reflective lenses deliver sharper images with better contrast. Enhancing Performance in Low-Light Conditions: In low-light situations, such as dawn or dusk, anti-reflective lenses make better use of minimal light, providing clearer views of the target.
