The Sig Sauer 3.5-10x42mm BDX-R1 With KILO1600 BDX pairs the SIERRA3BDX riflescope with the KILO1600BDX rangefinder to create a connected shooting system. The scope’s 3.5-10x magnification, 42 mm objective lens, and illuminated BDX-R1 digital reticle work with the rangefinder’s onboard ballistics to display an automatic holdover dot right in your sight picture, helping you line up confident shots at distance.

This combo is well suited for hunters and precision shooters who want a straightforward way to extend their effective range without complex dialing. The second focal plane design, generous 3.46 inch eye relief, and LevelPlex anti-cant system support steady field shooting, while the compact 6x22 mm KILO1600BDX slips easily into a pocket or pack. Together they offer a practical, modern solution backed by Sig Sauer’s reputation for dependable optics and thoughtful engineering.
