Sig Sauer Electro-Optics SOBBDX63102 BRAVO6T BDX Black 3-18x44mm, 35mm Tube, Illuminated MRAD Milling 2.0 Reticle
The Sig Sauer BRAVO6T BDX is a first focal plane rifle scope built around what Sig calls a ballistic computer—a heads-up display and onboard sensor suite that talk to your rangefinder and calculate hold-overs in real time. This is a 3-18x44mm scope with a 35mm tube, built for shooters who want precision without the mental math. It pairs a 6x magnification system with HDX optical glass (extra-low dispersion) and high-transmittance lenses for bright, sharp glass across varying light. If you're serious about long-range hunting or competition shooting and you already own a compatible Sig rangefinder, the BRAVO6T BDX removes a layer of complexity from field ballistics.
The real story here is the eTRAK elevation dial. It uses ZeroSync technology to sync with Applied Ballistics algorithms and your environmental conditions—pressure, temperature, humidity—measured by onboard sensors. Rotate the dial until the heads-up display shows your target distance, and you're ready to shoot. No charts. No range cards. No guessing whether you've accounted for wind or density altitude. The dial includes a multi-lock zero stop and tactile clicks (0.1 MRAD per turn) so you stay oriented in the field.
Connectivity is Bluetooth, with a 30-yard range to Sig's KILO BDX laser rangefinders and compatible devices. The scope runs on two 1/3N batteries and ships with an included ALPHA5 mount (1.250" height) for standard 20-MOA picatinny rails. It weighs 22.7 ounces, has 3.7–3.9 inches of eye relief, and delivers 50 MRAD of total adjustment travel in both elevation and windage—plenty of room for most hunting and competition applications. The reticle is illuminated MRAD Milling 2.0, and the whole unit is assembled in Oregon and backed by Sig's Infinite Guarantee.
