The riflescope choice of First Lite athlete and MeatEater team member, Jordan Budd, this scope is built upon the award-winning SIERRA3 platform and the SIG SAUER® BDX (Ballistic Data Xchange) technology. The SIERRA6 riflescope provides the hunter or marksmen with an intelligent auto-holdover specific to their ballistics, target, and environment, greatly improving accuracy and efficiency. Built with an advanced HDX 6x Optical System that provides crystal clear views with enhanced light transmission, this scope is also waterproof and fog-proof for exceptional performance in any environment or condition. Pair this riflescope with a BDX rangefinder to get Applied Ballistics capability without the need for a mobile device. Take your optics experience to the next level and dominate targets on the hunting grounds with the SIG SAUER® SIERRA6BDX 3-18x44mm.
