Frequently Asked Questions
Do I need a BDX rangefinder to use the Sierra4BDX? The scope functions as a standard variable-power optic on its own, but its BDX-R2 digital holdover dot requires Bluetooth pairing with a compatible SIG KILO BDX rangefinder to display a calculated aim point.
How is the digital reticle powered? The BDX-R2 digital focal plane and its 194 LEDs run on two CR2032 batteries.
