The Holosun HS507K X2 is a compact open reflex sight built for slimline and sub-compact pistol applications. It offers Holosun’s Multi-Reticle System, allowing the user to choose between a 2 MOA dot, 32 MOA circle, or circle-dot reticle depending on preference and application.
The HS507K X2 features Shake Awake technology, a side-loading battery tray, Lock Mode to help prevent accidental setting changes, and a durable 7075 aluminum housing. Its compact size makes it a strong option for concealed carry pistols, range use, and practical everyday setups.
This optic uses a red reticle, runs on a CR1632 battery, and is listed with up to 50,000 hours of battery life depending on setting and reticle selection. It is commonly associated with the Holosun K-series footprint, but pistol fitment should always be confirmed before ordering. Some optic-ready pistols may require an adapter plate or specific mounting screws.
