Don't let its ubiquitous form factor fool you, because hidden inside the Sig Sauer 6.5-20x52 SIERRA3BDX Riflescope are technological innovations that use Bluetooth connectivity to compatible devices that will give you the cool confidence to make a precise shot and ensure an ethical kill—even at long range and in challenging light.
Anchored on a free app for iOS and Android smartphones, Sig's Ballistic Data Xchange (BDX) system allows you to bond your mobile device with the scope and one of their KILO laser rangefinders and then pool a slew of information to plot a firing solution that is updated and displayed on the BDX-R1 digital ballistic reticle. The rangefinder gives you range and angle to the target while the app allows you to input the ballistic profile of your round as well as critical environmental data such as temperature and wind direction and speed. All the information is used to calculate an accurate elevation holdover and/or windage adjustment, which is sent to the riflescope. A dot is projected onto the reticle's crosshairs and all you need to do is place it on the target and fire. The scope can also be used without a rangefinder, utilizing the ballistic profile and environmental data to plot multiple aiming points at various distances. Since the dot is projected onto the reticle, the app adjusts the subtensions to the selected magnifications so they remain accurate through the entire zoom range.
Optically, the SIERRA benefits from an exceptional zoom range and a massive objective lens that enables you to precisely send shots at long range while enjoying bright and clear views even in low light or if you have the scope set on max magnification. Extra-low dispersion glass and broadband anti-reflection coatings maximize light transmission with virtually zero distortion across the whole field of view with enhanced color fidelity, contrast, and resolution. Capped low-profile turrets adjust at a precise 1/4 MOA per click with 20 MOA of travel per rotation and an adjustment range of 40 MOA. To withstand the repeated recoil of regular use and to provide the adjustment room required for the windage and elevation turrets, the one-piece maintube is made of lightweight but strong aluminum and is robust at 30mm in diameter. The housing is nitrogen filled and O-ring sealed to an IPX7 rating to make it waterproof, submersible, and resistant to internal fogging.
