At only 7 ounces (excluding the scope), the B3 EXACT 3D is one of the lightest sights you can find on the market. Quiet, precise, and durable, it boasts an all-machined metal body with laser-engraved scales, a 6" extension bar with the brand's signature click-in precision locators, and a fast-pitch elevation rod for quick vertical adjustments for different distances. In addition, for the vertical body, there are 3 macro-elevation positions combined with 2 inches of travel.
