Sig Sauer
The Sig Sauer SIERRA6BDX 3-18x44 riflescope brings Applied Ballistics ballistic calculation directly to your scope, eliminating guesswork at distance. This is a long-range hunting and precision shooting optic built for hunters and marksmen who need to dial accurate shots across varying terrain and conditions without reaching for a rangefinder app. The BDX-R2 digital system pairs with any BDX-equipped rangefinder to deliver automatic hold-over solutions tailored to your rifle's ballistics, ammunition, and the environment—centerfire, muzzleloader, and crossbow compatible.
Built on the award-winning SIERRA3 optical platform, the SIERRA6BDX combines a 6x magnification range (3–18x) with a 44mm objective and 30mm tube for bright, detailed images in low light and at distance. The advanced HDX optical system achieves up to 95% light transmission, keeping your image clear from dawn to dusk. Side-focus parallax adjustment gives you precision control over image sharpness at any range, while the 0.25 MOA per-click adjustment lets you dial in shots with fine accuracy. The scope is waterproof and fog-proof to IPX-7 standards—fully sealed and purged with argon gas for reliability in wet, cold, and field conditions.
The KinETHIC kinetic energy transfer indicator helps you make ethical shot placement decisions by showing whether your ballistic solution will deliver sufficient energy to the target. Levelplex with auto-leveling keeps your reticle aligned to true horizontal, a critical feature for long-range work where canting can throw your zero off. This is a premium scope for hunters who demand integrated ballistic intelligence and optical performance in one package.
| Magnification | 3–18x |
| Objective Lens | 44mm |
| Tube Diameter | 30mm |
| Reticle Type | BDX-R2 Digital on Second Focal Plane |
| Parallax Adjustment | Side focus |
| Adjustment Increment | 0.25 MOA per click |
| Light Transmission | Up to 95% |
| Waterproof Rating | IPX-7 (complete immersion to 1 meter) |
| Fog-Proof | Yes (argon purged) |
| Platform Compatibility | Centerfire, muzzleloader, crossbow |
| Color | Black |
The scope includes the BDX digital reticle and ballistic system, but to use the automatic hold-over feature you need to pair it with a Sig Sauer BDX-equipped rangefinder. Without one, you'll have a premium hunting scope with manual adjustment capabilities, but you'll lose the integrated ballistic intelligence that makes this optic special.
The SIERRA6BDX builds on the SIERRA3 optical foundation with the integrated BDX-R2 digital system for automatic ballistic calculation, a 6x magnification ratio (3–18x vs. the SIERRA3's range), and features like the KinETHIC kinetic energy indicator and Levelplex auto-leveling. It's designed for hunters who want ballistic data in the scope itself.
Yes. The 3–18x magnification, 44mm objective, and integrated ballistic system make this well-suited to long-range hunting applications where distance and environmental variables demand precise hold-over solutions. The 30mm tube provides the adjustment range you need for dialing elevation at distance.
