The HS403B is a small compact micro red dot optic. Employing Holosun’s LED technology, the lifetime for one CR2032 battery can be up to 30,000 hours. This optic features Holosun's “Shake Awake” technology that powers the optic on with slight movement of the 403B. It may be installed on various firearms such as shotguns, pistols ,air rifles and crossbows. The HS403B is compatible with standard mounts.
The HS403B replaced the previous HS403A in Holosun's lineup. The main differences include compatibility with industry standard mounts, and the battery location in the side of the optic instead of under the mount for an easier battery swap.
Features Holosun's Shake Awake™ technology. This great feature allows an optic to automatically go to sleep when the unit has not detected any type of movement or vibration in a specific amount of time that is programmable by the operator. Once the unit senses movement, it will automatically turn itself on and recall the last brightness that was used. This helps promote battery life further and insures the unit is on and ready when you need it!
