Holosun HS407K-X2 6 MOA Reflex Red Dot

The Holosun HS407K-X2 Reflex Red Dot Sight is an open-emitter pistol optic designed for subcompact handguns, featuring a single 6 MOA dot reticle for fast, intuitive aiming. Built as a 1x non-magnified optic, it provides a clear and unobstructed sight picture optimized for concealed-carry and everyday-carry pistol setups.

The HS407K-X2 is engineered to simplify sight acquisition while maintaining a compact footprint suitable for slim and subcompact slides. Its open reflex design preserves a wide field of view, helping shooters quickly locate the dot during presentation. The 6 MOA dot size is well suited for defensive distances, offering rapid visibility without reticle complexity. A parallax-free optical system with unlimited eye relief supports flexible head positioning and consistent point of aim during dynamic shooting.

Power management features are tailored for carry use. Shake Awake technology automatically activates the reticle when movement is detected and places the optic into a low-power state during inactivity to extend battery life. Lock Mode prevents accidental brightness changes while holstered, reducing the chance of unintended adjustments. A side-access battery tray allows the CR1632 battery to be replaced without removing the optic from the slide, helping maintain zero.

Constructed from 7075 T6 aluminum with a black anodized finish, the HS407K-X2 is built to withstand recoil, daily wear, and environmental exposure. The optic is rated IP67 for water and dust resistance and is specified by the manufacturer to handle high shock and vibration levels, supporting consistent performance on lightweight carry pistols.
