From the smallest and lightest line of Sightmark red dots comes the Mini Shot Pro Spec Reflex Sight, with an external battery compartment that makes re-zeroing unnecessary when replacing batteries and a hood protecting the lens from damage in the field. Five brightness levels make the 5 MOA dot clearly visible in any light condition, and the digital switch on the left side is easy to reach. You can expect up to 10,000 hours of runtime from one CR1632 battery, depending on brightness levels used. IPX4-rated water resistant, the Mini Shot Pro Spec is built of strong but lightweight aluminum and is equally at home on a pistol, shotgun, or modern sporting rifle.
