OPTISAN 04021 ES 3-12X44I
Step into the spotlight with the OPTISAN EVX 3-12X44I riflescope—developed using feedback from European shooting champions and engineered for shooters who demand precision in the field and at the range. Every component within this optic undergoes more than 200 rigorous in-house quality inspections to ensure exceptional reliability and performance under heavy recoil from calibers such as .308 and .300 Win Mag.
Building on the success of the original Viper series, the Gen II EVX platform delivers a 25% larger field of view and an accommodating eye box for faster and more comfortable target acquisition. The consistent 3.7″ eye relief across the full 3–12x magnification range ensures a stable cheek weld and dependable sight picture for improved shooting confidence.
Designed for accuracy and versatility, the EVX features matched mil/mil turrets and a redesigned mil-hash reticle for precise, repeatable adjustments and intuitive holdovers. Fully multi-coated lenses provide outstanding clarity and light transmission in both bright daylight and low-light conditions, making it suitable for hunting and long-range shooting.
Constructed from a one-piece aircraft-grade aluminum tube, the EVX is built to withstand harsh conditions with JIS7 waterproof protection and reliable operation in temperatures ranging from –20 °C to 50 °C. Push-pull lockable turrets with tactile 0.1 mrad clicks allow shooters to secure zero settings while maintaining quick adjustment capability in the field.
Whether you are hunting, competing, or improving your long-range accuracy, the OPTISAN EVX 3-12X44I offers the precision, durability, and optical clarity serious shooters demand.
