CRS is an enhanced multi-reticle system with four components including a precision 2MOA dot, an 8MOA circle, 20MOA circle, and 32MOA circle with multiple combination settings to suit individual shooter preference. 507Comp-RD/507Comp-GR is made from 7075 aluminum with an industry standard footprint, and includes Shake Awake technology
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.
