Sig Sauer Electro-Optics (SIG EO) is releasing a new line of SIERRA6BDX hunting scopes that combine relatively light weight with advanced features and up to 95% light transmission. We think hunters may see the advantages of a “smart scope” which offers ballistics and windage info in a relatively streamlined form factor with a 6X zoom ratio. These scopes calculate an aim point and wind hold-offs.

There are currently three SIERRA6BDX riflescope models: 2-12x40mm, 3-18x44mm, and 5-30x56mm. All three have 1/4-MOA clicks. We think many hunters will prefer the 2-12x40mm optic which is the lightest at 21.7 ounces, as well as the least expensive at $1169.99 MSRP. Twelve power is plenty for a hunter. Designed “by hunters for hunters”, SIG’s new SIERRA6BDX riflescopes offer some very advanced features:

1. LevelPlex™ — a built-in Digital Level that displays rifle cant.
2. QuickBOND™ allows SIG BDX rangefinders to “talk” to the scope without needing a Smartphone App (30 yard range).
3. Digital Focal Plane BDX-R2 hunting reticle with wind holds and 194 LEDs.
4. KinETHIC™ display shows Kinetic Energy Transfer to target.

How the BDC System Works
These scopes all feature SIG Sauer’s smart on-board BDC system which is user-selectable for cartridge (there are 9 options). Selection of the appropriate BDC is explained starting at 1:15 in the video below. You use the illumination control knob to select the right BDC for your cartridge. Then you manipulate the zoom control lever to “lock in” your choice. A wide variety of information is displayed in the illuminated reticle.

SIG states: “Our mission with the new SIERRA6BDX riflescope line was to bring all of the advanced features of the BDX 2.0 platform to a premium 6X zoom system. BDX 2.0 takes all of the advanced Applied Ballistics Ultralight and Bluetooth™ technology and adds simplified, and easy to use, functionality to get hunters and shooters on target with unprecedented speed and accuracy. The BDX 2.0 System is simple, fast, and intuitive — just connect the dot.”
