Sightmark Ultra Shot Reflex Sight The Sightmark® series of reflex sights are designed to create a lightweight, yet extremely accurate sight. The Ultra Shot™ is Sightmark’s biggest and baddest sight in the reflex line, while still being incredibly lightweight for its size. Perfect for shotguns or rifles, the Ultra Shot comes with a built-in, integrated Weaver mount, which fits all standard bases, and is able to withstand heavy recoil from larger calibers or an 11mm Dove Tail mount option. This, with the ability to choose between 4 different reticle patterns, makes the Ultra Shot an unusually versatile sight. With a wider field of view than any other reflex sight on the market, and a Limited Lifetime Warranty, the Sightmark Ultra Shot is literally in a class by itself!
