Sig Sauer Electro-Optics SOBBDX63104 BRAVO6T BDX Black 3-18x44mm, 35mm Tube, Illuminated MRAD DEV-L 2.0 Reticle
The Sig Sauer BRAVO6T BDX is a 3-18x44mm first focal plane scope built for shooters who demand ballistic computing power without leaving the eyepiece. This isn't just glass and steel—it's an integrated fire control system that fuses a premium riflescope with a real-time ballistic computer, making long-range precision faster and more intuitive when it counts.
What sets the BRAVO6T apart is its eTRAK elevation dial, paired with ZeroSync technology and Applied Ballistics integration. As you rotate the dial, an onboard environmental sensor suite (measuring pressure, temperature, and humidity) continuously updates your ballistic solution. The heads-up display shows you the current shoot-to distance in your field of view—no range cards, no mental math, no looking away from the target. Bluetooth connectivity (up to 30 yards) links the scope to compatible KILO BDX rangefinders and other devices, feeding real data into the calculation. Simply dial until the display matches your target distance and break the shot. The 35mm tube and 6x zoom (3–18×) deliver a bright, sharp image across varied light using Sig's HDX optical system, while the illuminated MRAD DEV-L 2.0 reticle keeps you on target in low light. The scope arrives ready to mount with an included ALPHA5 mount and is assembled in Oregon.
This is a scope for serious long-range hunters and precision shooters who've invested in quality glass and now want the computational advantage to match. It's also backed by Sig Sauer's Infinite Guarantee.

Frequently Asked Questions
Can I use the BRAVO6T BDX with my rangefinder?
Yes. The scope features Bluetooth connectivity (up to 30 yards) and integrates with compatible KILO BDX laser rangefinders and other devices. Range data feeds directly into the ZeroSync ballistic computer to update your shot solution in real time.
What does the heads-up display show, and do I have to look away from my target?
The heads-up display is low-profile and positioned within your field of view, showing the current shoot-to distance calculated by the ballistic computer. You don't need to reference range cards or external devices—simply dial the eTRAK until the displayed distance matches your target distance, all without breaking cheek weld.
Does this scope come with a mount?
Yes. The BRAVO6T BDX ships with an included ALPHA5 mount (1.250 in diameter) and LRF diving board, ready to install on your rifle.
What batteries does the BRAVO6T BDX use?
The scope runs on two 1/3N batteries, which power the illuminated reticle, environmental sensors, and digital display.
