The Sightmark series of reflex sights are designed to create a lightweight, yet accurate, sight. The Ultra Shot is Sightmarks 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 calibers. 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!
