The HE407K Reflex Sight represents an innovative open reflex optical sight tailored specifically for subcompact pistol use. Building upon its predecessor, this model introduces Lock Mode, a feature initially introduced in our 2018 LEM pistol optic line. Activation of Lock Mode safeguards against unintended adjustments by securing the buttons.

Key attributes include Holosun's Green Super LED, boasting an impressive battery life of up to 50,000 hours, along with a clear 6MOA dot and Shake Awake functionality. Crafted from robust 7075 Aluminum, the housing incorporates Holosun's K footprint and facilitates easy battery replacement via a side-mounted tray for 1632 batteries.
