NcStar STM3942GV2 Mark III Tactical 3-9x42mm Mil-Dot Scope

The NcStar STM3942GV2 Mark III Tactical Gen 2 delivers precision optics at an accessible price point for tactical applications and precision shooting. This variable power scope combines proven magnification range with military-standard reticle patterns for versatile performance across multiple shooting disciplines.

What Makes This Different

The Mark III Tactical Gen 2 features an upgraded optical system with fully multi-coated lenses that transmit 95% of available light for enhanced clarity in low-light conditions. The hardcoat anodized finish provides superior corrosion resistance compared to standard anodizing processes, while the nitrogen-purged tube construction eliminates internal fogging. Fast-focus eyepiece adjustment allows rapid target acquisition without compromising eye relief.

Key Features

• 3-9x variable magnification with 42mm objective lens for versatile range applications
• Mil-Dot reticle system enables accurate range estimation and holdover calculations
• Fully multi-coated optics maximize light transmission and image clarity
• Hardcoat anodized aluminum construction resists wear and environmental damage
• Nitrogen-purged and O-ring sealed for complete waterproof performance
• Standard 1-inch tube diameter fits most tactical ring systems
• Capped turrets provide secure adjustment retention during transport

Field performance centers on the scope's ability to maintain zero through temperature variations and recoil stress. The internal adjustment mechanism provides 60 MOA of total travel in both windage and elevation, accommodating various ammunition types and shooting distances. Law enforcement and competitive shooters benefit from the precise click adjustments and repeatable tracking. The 42mm objective lens gathers sufficient light for dawn and dusk operations while maintaining a compact profile.
