Osight K GN by OLIGHT combines simplicity, durability, and practical features in one compact housing. Its large 21 × 14 mm viewing window provides a wide field of view for fast target acquisition without sacrificing situational awareness. The 6 MOA green dot is ideal for dynamic shooting and precise hits at short distances. Thanks to the side-loading CR1620 battery compartment, the battery can be replaced without removing the sight, preserving your zero. The body is machined from 7075-T6 aerospace-grade aluminum for exceptional impact resistance and durability, while the IPX6 rating protects against water exposure. A built-in motion sensor automatically wakes the optic when moved and puts it into sleep mode after 3 minutes of inactivity to maximize battery life. FMC multi-coated lenses deliver a clear, high-contrast image even in challenging lighting conditions.
