Drawing on its tradition of optical craftsmanship, engineering excellence, and precision manufacturing, Leica delivered the 1.8-12x50 Magnus i Riflescope to empower you with uncompromising lasting durability and safety, brilliant optical performance, and precision. At the core of this riflescope is an expertly designed optical system with precision optical elements that provide high-contrast and crystal sharp images. To enhance optical performance and to bring total light transmission to 91%, the optical system is outfitted with fully multi-coated elements and a baffle system to reduce stray light. To protect lenses from moisture and to ensure clear views during adverse weather conditions, optical surfaces are enhanced with the Aqua-Dura hydrophobic coating that repels water droplets. With the 50mm objective, this riflescope can become a reliable partner for making that perfect shot in the most challenging of lighting conditions. This riflescope offers all necessary convenient features like a generous eye relief and a diopter adjustment.
Another central highlight of this scope is the L-4A Reticle. Inspired by the German # 4 style, the reticle offers three medium posts, a thin crosshair, and an illuminated ultra-fine yet well-defined, brilliant red center dot. The dot's brightness offers 60 settings and can be adjusted to accommodate your preferences and any lighting conditions. The crosshair line casts a 0.2" (0.5cm) subtension and offers a 55" (140cm) center gap in the field of view. The reticle also offers a parallax-free performance at 100 yards. To save battery power, the auto-off function is activated when you tilt the rifle 75° or after 3 minutes of inactivity.
To ensure lasting durability for years of service, the housing is almost over-engineered. It is made from high quality aluminum alloy and features a 30mm maintube with a 1.5mm thick wall for exceptional strength and safety. Among other highlights are waterproof and fogproof performance, low-profile capped turrets that can be re-zeroed without tools, knurled and easy-to-operate in gloves knobs and rings, slim eyepiece, and a redesigned for efficiency battery compartment. The magnification ring also features a low-profile lever, just in case you need to bump up that zoom factor instantly.
