OSight K Features The OSight K s 6 MOA green dot stands out sharply in bright environments enabling rapid draw confident aim and immediate engagement. A motion sensor function powers the optic on at the slightest movement and powers down after 3 minutes of inactivity to conserve battery extending runtime between charges without any manual switching. A side-loading battery design allows effortless battery replacement without removing the optic from the slide ensuring hassle-free re-zeroing when the CR1630 battery needs to be swapped. For concealed carry users who need fast target acquisition in bright conditions the OSight K s 6 MOA green dot delivers that visibility for rapid confident engagement. Fitting directly to RMSc cut optics-ready slides the compact optic delivers exceptional compatibility ensuring seamless integration across a multitude of pistol builds. A sleek streamlined battery tray keeps the sight comfortable to carry and quick to draw ideal for concealed or duty use. When battery voltage drops below 2.2V the reticle will quickly triple-flash once per minute to recommend an imminent battery replacement giving shooters advance warning before the optic goes dark. For duty professionals who need advance warning before their optic loses power the OSight K s low power indication delivers that peace of mind in the field.
