Holosun 507K X2 Micro Green Dot Sight

The HE507K-GR X2 is an open reflex optical sight designed for subcompact pistol applications. The HE507K-GR X2 improves on previous the version by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes. Additional features include Holosun's Green Super LED with up to 50k hour battery life, Multi-Reticle System, and Shake Awake. The durable housing is made from 7075 Aluminum, uses Holosun's K footprint, and houses the 1620 battery in a side-mounted tray for easy replacement when needed. The HS507K X2 is a direct fit for Sig P365X/XL.
