SIG SAUER Bravo6 TBDX 3-18x44mm 35mm Tube Rifle Scope First Focal Plane MRAD Dev-L 2.0 Illuminated Black. SIG SAUER s all-new eTRAK elevation dial leverages ZeroSync technology to monitor user input and manipulate the calculated shoot-to distance in the optic s heads-up display eliminating the need to reference charts or range cards. Simply rotate the eTRAK dial until the displayed shoot-to distance corresponds with the target distance and engage without ever leaving your cheek weld. ZeroSync connects the eTRAK elevation dial with the power of Applied Ballistics while accounting for prior adjustments and providing a custom solution that always represents the current conditions and ensures ease of operation when tenths of a second matter. Powered by a 6x magnification optical system the BRAVO6T-BDX delivers a sharp bright image using SIG SAUER s proven HDX lenses for unrivaled performance in varied light.
