Description
Holosun HE407C-X3-GR2 407COMP X3 Green Dot Open Reflex Sight – 2 MOA Dot, RMR Footprint
The Holosun HE407C-X3-GR2 is a compact open reflex pistol sight built for concealed carry, duty applications, competition, and range shooting. Featuring a crisp 2 MOA green dot, this optic offers precise aiming while remaining fast to acquire for close-range shooting and rapid target transitions.
The true 1X magnification provides a natural both-eyes-open sight picture, while the low-profile housing is designed to fit modern optic-ready pistols. Built around the popular RMR footprint, the HE407C-X3-GR2 is compatible with many RMR-cut slides and mounting plates.
The green reticle provides strong contrast in bright conditions and visually busy environments. Holosun’s Solar Failsafe technology uses ambient light to support optic operation, while automatic brightness adjustment helps maintain reticle visibility in changing light conditions.
The side-mounted CR1632 battery tray allows convenient battery replacement without removing the optic. Shake Awake technology activates the sight when motion is detected, while Memory Mode retains the previous brightness setting. Lock Mode helps prevent accidental button changes during carry, training, or shooting.
Constructed from rugged 7075-T6 aluminum with a black anodized finish, the HE407C-X3-GR2 is built for reliable performance under recoil and harsh weather conditions. Its IP67 waterproof rating provides added protection against water and dust.
