This open reflex sight (mini) with red reticle offers a multi reticle system with switchable reticles (2 MOA/32 MOA) and a durable aluminium housing. This optic has the same line of sight to the rear sight / front sight. It’s ideal for pistols/short weapons and 15m drop plate shooting (shotgun).

Holosun’s reflex sights are high-quality optics to military standard at an unbeatable price – without compromises. All models feature an intelligent Shake Awake™ function for an exceptionally long battery life, absolute parallax freedom, a tilted front lens (Micros and Tubes), and 12 brightness levels (2 night, 10 day) for manual adjustment of brightness under different lighting conditions. Holosun Red Dot Sights can be used in combination with laser targeting systems, night vision devices, and night vision goggles.

The X2 series expands the existing functions for automatic and manual modes with an innovative lockout mode (only solar failsafe models have automatic mode). The lockout mode locks the buttons and prevents accidental changes to the settings.

The 32 MOA circle of the HS507K-X2 is unique, as opposed to the usual 65 MOA circles, in that its diameter is the same size as the diameter of a steel falling plate in the BDS falling target discipline with a shotgun at a distance of 15m. This results in a very quickly perceived sight picture and therefore extremely short split times in this discipline.

Shake Awake™

Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use.

This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.
