The SIERRA3BDX 2.5-8x32mm is a compact and lightweight riflescope designed for ultra-lightweight rifle, shotgun muzzleloader, and crossbow configurations.

Featuring exceptional SpectraCoat™ lenses, LevelPlex™ digital anti-cant, and KinETHIC™ kinetic energy transfer indicator, the SIERRA3BDX 2.5-8x32mm is incredibly simple to use. Range a target, put the holdover dot on target, pull the trigger, impact.


– Integrated BDX™ Ballistic Data Xchange. A rangefinder and riflescope system that uses ballistics, environmental conditions and Bluetooth® to illuminate the exact holdover dot.

– Automatic holdover dot on a Digital Focal Plane™, combining Second Focal Plane stadias, with an OLED illuminated ballistic holdover dot that automatically scales with zoom to subtend on target at any magnification level.
