Holosun HE507K-GR X2 Compact Pistol Sight HE507K-GR X2

The Holosun HE507K-GR X2 is an open reflex green dot sight designed specifically for subcompact handguns, offering a slim profile without sacrificing performance. Built from durable 7075 aluminum, this optic features a wide viewing window and compact dimensions, measuring about 1.6 inches long, 0.98 inches wide, and 0.95 inches tall, with a lightweight design of just 1 ounce.

The HE507K-GR X2 introduces Lock Mode to prevent accidental setting changes and is equipped with Holosun’s Multi-Reticle System, giving shooters the option of a precise 2 MOA dot, a 32 MOA circle, or a combination of both. The 540nm Green Super LED provides a crisp, bright aiming point with up to 50,000 hours of battery life on a single CR1632 cell. A convenient side-loading battery tray allows for easy replacement without removing the optic.

Engineered for reliability in carry conditions, the sight includes Shake Awake motion sensing to conserve battery life and automatically activate when needed. It uses Holosun’s K footprint for secure mounting and directly fits the Sig Sauer P365 X/XL series, with adapter plates available for other handguns with a four-boss interface.

With rugged construction, long battery life, and versatile reticle options, the Holosun HE507K-GR X2 delivers speed, clarity, and confidence in a compact reflex sight built for concealed carry.
