OPTISAN 04020 ES 10X44I

Meet the OPTISAN 04020 ES 10X44I—a precision scope born from direct collaboration with Europe’s top competitive shooters. We inspect every one of the 90–150 components through over 200 rigorous in-house quality checks, ensuring your optic endures harsh recoil and rugged field use without compromising performance.

The redesigned EVX Series outshines the original 2006 Viper line with true sub-MOA accuracy. Whether you’re chasing match victories or hunting at first light, this fixed 10X magnifier delivers a 25% wider field of view for lightning-fast target acquisition. A generous eye box and a consistent 3.8″ eye relief across every shot keep your head steady—no awkward repositioning when split-second adjustments matter most.

STATE-OF-THE-ART OPTICS
Featuring fully multi-coated lenses, the GEN II optical system maximizes light transmission and produces razor-sharp resolution in all conditions. Brake for nothing—.308 Winchester and .300 Weatherby Magnum recoil are no match for its shock-resistant build.

PRECISE, RELIABLE ADJUSTMENTS
Lockable mil/mil turrets offer crisp 0.1 mrad clicks and 4.8 mrad per rotation travel. Pop the controls up or push them down to lock settings instantly. Choose between first or second focal plane reticles, each sporting a redesigned mil-hash pattern for rapid ranging and holdover accuracy.

BUILT FOR EXTREMES
Crafted from one-piece aircraft-grade aluminum and finished in matte black, the 30 mm tube is waterproof (JIS7), fog-proof and nitrogen‐purged. It thrives in temperatures from -20 °C to 50 °C, weighs just 693 g (24.4 oz) and measures a streamlined 338 mm (13.3″) in length—perfect for heavy-recoil rifles and backpacking hunts alike.

ADVANCED ERGONOMICS
Fine-tune focus with a +2/-2 diopter range and parallax adjustment from 10 yds to infinity (parallax-free at 100 yds). Six-step illumination with off-settings between levels means crisp reticle visibility from dawn to dusk.

In the box, you’ll find a 3″ sidewheel, 3″ sunshade and rugged metal flip-up covers—accessories ready to be slotted into your shooting system. Elevate every shot to championship pedigree with the OPTISAN 04020 ES 10X44I.
