Holosun 507K X2 Green Dot Sight, 2 MOA Dot & 32 MOA Circle

Holosun 507K X2 Green Dot Sight Features and Performance

The Holosun 507K X2 green dot sight is built for shooters who want a compact, dependable pistol reflex sight for slimline and micro-compact handgun setups. Also searched as the HS507K, Holosun 507K, or simply 507K, this optic uses the Holosun K footprint and gives compatible optic-ready pistols a clean aiming upgrade without adding unnecessary bulk.

The selectable green Multi-Reticle System lets you choose a 2 MOA dot, 32 MOA circle, or combined circle-dot reticle. The dot gives you a more precise aiming point for controlled shots, while the circle or circle-dot view helps with faster reticle pickup at close range. With 1x magnification, parallax-free aiming, unlimited eye relief, and multi-coated glass, the Holosun 507K X2 is designed for fast, natural shooting from different positions.

The feature set is practical for a compact carry optic. Shake Awake helps conserve battery life by powering the reticle down during inactivity and bringing it back when movement is detected. The side-loading CR1632 battery tray allows battery changes without removing the optic from the firearm, helping preserve zero. Manual brightness controls, memory function, auto off, and lockout mode help keep the optic simple to use once it is mounted.

The Holosun 507K X2 uses a 7075-T6 aluminum housing with an anodized black finish, IP67 submersion rating, and 5000G vibration rating. It offers 10 daylight and 2 night vision brightness settings, up to 50,000 hours of battery life, 1 MOA click adjustments, and ?30 MOA windage and elevation travel. At only 1 oz, with a 0.58" ? 0.77" window and compact 1.6" ? .98" ? .95" body, it is built for smaller pistol setups where size and weight matter.

Choose the Holosun 507K X2 green dot sight when you want a compact K-footprint optic with a selectable reticle, side battery tray, Shake Awake, durable housing, and a clean sight picture for carry, range use, or defensive practice.
