OPTISAN 37504 HX 4-12X40 DUPLEX Elevate your shooting game with the OPTISAN HX 4-12X40 Duplex—the optic forged alongside European champions to thrive under competition pressure and endure the harshest field conditions. From concept to your rifle, each scope is born from rigorous in-house testing: 90–150 precision components, over 200 quality checks, and constant refinement ensure uncompromising reliability. The HX series welcomes both seasoned hunters and weekend warriors with a design that offers 25% more field of view than standard 3-9X40 scopes—so you’ll spot game and targets faster and with greater confidence. Built on a one-piece aircraft-grade aluminum tube, this scope handles hot magnum calibers (.270 Win, .308, .30-06) with rock-steady consistency. Fully multi-coated lenses maximize light transmission for crisp, bright images from dawn patrol to dusk hunts. Customize your aiming solution: choose the classic Duplex reticle for a clean, timeless crosshair or opt for the Ballistic Compensated Reticle (BCR) to dial in precise holdovers out to 500 yards. Rimfire and air-rifle enthusiasts will appreciate the 4-12X40 AO variant, parallax-free at 35 yards, complete with an enhanced Mildot reticle for pinpoint accuracy on steel silhouettes and targets. Windage and elevation adjustments are intuitive and tool-free, featuring low-profile turrets with finger-resettable zero so you can quickly recalibrate in the field. Smooth 1/4 MOA clicks let you fine-tune your point of impact, while a generous 3.5″–3.3″ eye relief keeps you safe from recoil. The matte-black finish minimizes glare and withstands rough handling and extreme temperatures from –20°C to 50°C. Whether you’re stalking deer in dense timber or ringing steel at the range, the OPTISAN HX 4-12X40 Duplex is your partner in precision.
