Holosun HS507C-X2 2 MOA / 32 MOA Reflex Red Dot Sight

Holosun HS507C-X2 Reflex Sight is an open-emitter red dot optic designed for pistol mounting, delivering a fast, repeatable point of aim for handgun applications. This compact reflex sight uses a selectable reticle system and redundant power options to support duty, range, and defensive pistol setups where a low-profile optic is preferred.

The HS507C-X2 is built to provide an electronic aiming solution for full-size pistols that require an RMR/SRO footprint. Its primary function is to give the shooter flexibility in reticle choice while maintaining a clear, unobstructed sight picture. Using the Multiple Reticle System, the optic allows the user to select a 2 MOA center dot, a 32 MOA circle, or a combined circle-dot reticle depending on preference and shooting context. This makes it suitable for both precision-focused shooting and rapid target acquisition in dynamic environments.

Specifications & Build

The HS507C-X2 features a 7075-T6 aluminum housing with a black anodized finish for durability and wear resistance. The optic uses multi-coated lenses to maintain clarity and reduce glare. Windage and elevation adjustments offer a reported total travel range of up to 150 MOA, allowing flexibility for slide and mounting tolerances. The unit is rated IP67 for water resistance and is tested to withstand up to 5000G of vibration, supporting use on duty and service pistols.

Compatibility & Use

This reflex sight is compatible with pistols and mounting systems that accept the RMR/SRO footprint. It is commonly used on full-size duty pistols, patrol handguns, competition pistols, and range setups where a compact, open red dot optic is desired. The sight is intended for direct slide mounting or use with compatible adapter plates, depending on the pistol platform. Mounting hardware is not included, so slide configuration or plate compatibility should be verified prior to installation.
