The Trijicon 1-6x24 VCOG (variable combat optical gunsight) is engineered for durability and versatility, offering variable magnification suitable for both close-quarter combat and long-range shooting. Constructed with a forged aircraft-grade 7075-T6 aluminum housing, the VCOG is exceptionally robust. Its high-quality optics deliver outstanding clarity and color fidelity without distortion. The universal segmented circle/MIL reticle is optimized for multi-platform compatibility, supporting various calibers, ammunition types and barrel lengths. The first focal plane reticle ensures that subtensions and ballistic drops remain accurate across all magnification levels, enabling precise and rapid target acquisition. Equipped with ruggedized electronics, the LED reticle is designed to withstand demanding conditions. It operates on a supplied lithium AA battery, offering six user-selectable brightness levels. The green LED provides a battery life of 1400 hr at setting 4 (constant on), while the red LED offers 700 hr. An integrated dial fin facilitates smooth magnification adjustments and consistent eye relief eliminates the need for head or stock position changes. The unit is waterproof up to 20 m (66 feet). Lenses with multiple coatings offer exceptional clarity and enhanced light-gathering abilities, ensuring distortion-free performance The device has undergone MIL-STD-810G testing, a U.S. Department of Defense-approved series of tests designed to replicate field conditions The first focal plane reticle enables users to swiftly acquire targets and maintain accurate holdovers across the entire magnification range The reticle, featuring exceptional illumination, operates efficiently using a single AA battery, ensuring optimal visibility and performance The 1-6x24 model provides BDC, Universal MRAD, and MOA reticles, while the 1-8x28 model features Universal MRAD and MOA reticles Enables users to efficiently modify windage and elevation settings, ensuring precise adjustments for optimal performance and accuracy The integrated mounting adapter eliminates the need for traditional ring mounts, enabling swift and effortless attachment to any rail system The product is designed for compatibility with a wide range of market-available rails, specifically engineered to accommodate the Trijicon ACOG The 1-8x28 models offer (11) brightness settings, while the 1-6x24 models provide 6 settings, each with an "off" option between adjustments The integrated dial fin facilitates seamless rotation through various magnification settings, ensuring precise and effortless adjustments for optimal viewing
