Overview
The Osight K is purpose-built for defensive pistol use, where speed and visibility matter most. Its bold 6 MOA dot is easy to pick up during rapid draws and high-stress scenarios, helping shooters achieve faster alignment and confident first-shot placement.
Fast, Visible 6 MOA Dot
A larger dot reduces visual hunting during the draw and recoil cycle. The 6 MOA reticle promotes consistent presentation and rapid engagement, making it ideal for concealed carry, home defense, and close-range training.
Easy Battery Access, No Re-Zero
The side-loading CR1620 battery tray allows quick replacement without removing the optic from the slide, helping you keep your zero intact and your setup consistent.
Smart Power Management
A built-in motion sensor instantly activates the optic when movement is detected and powers it down after approximately 3 minutes of inactivity to conserve battery life.
Low Battery Warning
When battery voltage drops below 2.2V, the reticle will triple-flash once per minute, providing a clear visual reminder that it’s time to replace the battery.
