The Zero Compromise Optic ZC840 8-40x56 FFP Illuminated CCW MPCT2X 0.1MIL Rifle Scope represents the pinnacle of precision optics, setting a new benchmark for magnification, imaging performance, and mechanical accuracy. Designed for professional marksmen and long-range shooting enthusiasts, the ZC840 delivers unparalleled resolution and optical clarity, ensuring that no detail is ever missed.
With a versatile 8-40x magnification range, this rifle scope provides extreme flexibility for both mid-range and ultra-long-range engagements. The 56mm objective lens ensures exceptional light transmission, boasting an impressive 92% efficiency, guaranteeing bright, high-contrast images even in low-light conditions. The field of view spans 4.6m to 1.0m per 100m, ensuring situational awareness while maintaining focus on your target.
At the core of this scope is the MPCT2X reticle, a cutting-edge design optimised for precision shooting. This minimal tree-style reticle features an open concept above the primary horizontal crosshair, enhancing target acquisition and allowing for easier trace spotting as bullets travel downrange. The vertical crosshair extends up to 3.0 MILs for effective hold-under capability, while 0.2 MIL hash marks across the reticle aid in rapid identification of hold points. Floating dots at each full MIL interval further enhance precision aiming, making this reticle intuitive and incredibly fast to use in demanding field conditions.
Mechanically, the ZC840 excels with an elevation adjustment range of 27 MILs and windage adjustment of 12 MILs, providing shooters with extensive correction capabilities. The 0.1 MIL click values ensure micro-adjustments are precise, while the CCW turret rotation enhances ergonomic operation. Elevation and windage turrets are fully lockable, ensuring settings remain secure even in dynamic environments. The parallax adjustment starts from just 10 metres to infinity, accommodating both close-quarters and extreme-range shots.
Durability and reliability are at the forefront of the ZC840’s design. Built with a robust 36mm main tube, it is waterproof to 4 metres and engineered to perform in extreme temperatures ranging from -25°C to 60°C. The scope’s automatic illumination management system intelligently powers down the illuminated reticle after two minutes of inactivity or based on movement, with a complete shutdown after two hours to preserve battery life. The reticle illumination, available in red and green, is powered by a CR2032 battery, ensuring consistent performance in all lighting conditions.
With a total length of 440mm and weighing 1175g, the Zero Compromise Optic ZC840 is a masterclass in optical engineering, offering a perfect balance between high-performance features and rugged dependability.
