ED 3-18x50SFPIR Stisa optics Rifle Scope TRUESHOT Tube30mm

High-Strength Eco-Friendly Aluminum Alloy

Made from high-strength eco-friendly aluminum alloy with an integrated structure and anodized finish for exceptional durability. Features an etched illuminated glass reticle, IPX67-rated waterproof and dustproof, with nitrogen purging to prevent fogging, ensuring stable and reliable performance.

Anti-Fog Technology

The STISA rifle scope uses nitrogen purging technology to effectively prevent internal fogging. By replacing moisture-laden air inside the scope with nitrogen, it avoids fog caused by temperature changes, ensuring a clear view under all environmental conditions and improving shooting accuracy and reliability.

Impact Resistance

After firing 1,000 rounds of 7.62×51mm live ammunition at 100 yards, the deviation is less than 0.75 MOA with no significant shift in the point of aim. The lenses and internal optical components remain intact with no damage or displacement, maintaining optical clarity and brightness. External protective elements and internal mounting systems show no loosening or damage, ensuring long-term aiming stability.

Waterproof Performance

The STISA scope is rated IPX7 waterproof, capable of withstanding immersion up to 1 meter deep for 30 minutes without damage. This rating guarantees reliable operation in harsh weather and humid environments, meeting outdoor use requirements.

Anti-Reflective Lenses

Enhances light transmission by minimizing surface reflection, allowing more light to enter the scope and improving image brightness. The anti-reflective coating significantly reduces glare and reflections in strong or backlighting conditions, preventing viewing interference. It minimizes reflected and scattered light to deliver clearer images and better contrast, enhancing visibility in low-light environments.

Reticle and Turret Precision

This scope offers up to 99% rotational precision, ensuring every click results in accurate adjustment. The high-precision design helps users calibrate the aiming point more accurately, significantly improving reliability and accuracy, especially for long-range shooting.
