Sig Sauer Sierra3 BDX 3.5-10x42mm 30mm Tube Illuminated BDX-R1 Reticle KILO Compatible

The Sig Sauer SIERRA3BDX Sierra3 BDX Black Anodized 3.5-10x42mm 30mm Tube Illuminated BDX-R1 Reticle delivers an illuminated auto-holdover dot when paired with a BDX-capable KILO rangefinder, integrating ballistics, environmental conditions, and Bluetooth to illuminate the exact holdover dot while a Second Focal Plane reticle scales with zoom for precise aiming at any magnification. This scope features MOTAC motion-activated illumination for extended battery life and safety, SpectraCoat anti-reflection lens coatings for superior light transmission, and SIG SAUER's KinETHIC kinetic energy transfer indicator to help ensure ethical shot opportunity by signaling when energy on target falls below a hunter-set threshold. Auto LevelPlex enhances digital level sensitivity on longer shots, and the rugged design is IPX-7 waterproof and fog-proof for reliable performance in harsh field conditions. With a 30mm tube, 42mm objective, 3.46 inches of eye relief, and a weight of 20.90 ounces, the optic provides a generous field of view at 9.40 to 27.80 feet per 100 yards and a practical length of 12.75 inches, making it a versatile choice for mid- to long-range hunting under varied light.
