The Holosun 507K-X2 is a compact open reflex sight designed for micro-compact pistols, offering a 32 MOA ring and 2 MOA dot reticle for fast and accurate target acquisition. Built for concealed carry and everyday reliability, it delivers rugged performance in a lightweight, low-profile package. Featuring Holosun’s Shake Awake™ technology, the 507K-X2 automatically powers on when motion is detected and off when idle, maximizing its impressive 50,000-hour battery life. The side battery tray allows quick battery changes without removing the optic, while 12 brightness settings, including 2 night-vision compatible modes, ensure clarity in any lighting environment. Constructed from 7075-T6 aluminum with a durable black finish, the 507K-X2 is engineered to handle heavy recoil and harsh conditions. Compact, efficient, and precision-built, it’s an ideal upgrade for modern concealed carry pistols like the SIG P365, Springfield Hellcat, and Glock 43X MOS.
