HOLOSUN support FAQ

Common questions about manuals, registration, and support for this brand.

  • How does the Shake Awake technology work?

    The sight automatically enters sleep mode after a set period of inactivity to conserve battery. It instantly wakes up and powers on the standard reticle setting when it detects any motion or vibration.

  • What type of battery do Holosun sights typically use?

    Most Holosun micro sights and reflex sights use a single CR2032 Lithium battery. Refer to your specific model's manual for installation instructions and polarity orientation.

  • How do I cycle the reticle on a Multi-Reticle System (MRS) optic?

    On models equipped with MRS, you can typically cycle between the Dot, Circle, and Circle-Dot reticles by holding down the '-' (minus) brightness button for 3 seconds.

  • What is the Holosun Limited Lifetime Warranty?

    Holosun warrants that the metal structure and optical glass of their products will be free of defects in materials and workmanship for the lifetime of the product under normal use. Electronic components and other materials may have different warranty terms.
