Holosun Technologies Reflex 407K-X2 Red Dot Optical Sight
Small footprint. Big performance. Always ready.
The Holosun HS407K X2 is a micro-sized 6 MOA red dot reflex sight designed for subcompact pistols like the Sig P365X/XL, offering rapid target acquisition and enhanced concealment carry performance. Built from 7075-T6 aluminum with a hardcoat anodized finish, this rugged sight incorporates Lock Mode to prevent accidental brightness or reticle adjustments during use.
The Red Super LED and Shake Awakeâ„¢ technology deliver an impressive 50,000-hour battery life, with motion-activated power and auto-sleep functionality. The parallax-free optical design with unlimited eye relief ensures fast, repeatable accuracy, and the side-loading CR1632 battery tray allows for simple battery changes without removing the optic or re-zeroing.
With 12 brightness settings (10 daylight, 2 night vision), the HS407K X2 adapts to any lighting condition and mounts using the Holosun K footprint, making it ideal for slim-profile pistols.
