Experience the hunting trip of a lifetime with confidence by using the SIG Sauer BDX ballistic-calculation system. The patented system found in the Kilo1000 BDX LRF and Sierra3BDX 4.5-14x50mm riflescope combo kit takes the guessing out of ethical and precise shots, even in unfamiliar territory. Weighing in at a lightweight, this optic provides the benefits of modern ballistic-calculation technology while not weighing down your rifle system.

The BDX system works together by implementing your rifle and ammo configuration with range and windage data taken from the Kilo1000 BDX rangefinder. The software calculates the shooting solution and sends it to your Sierra3BDX riflescope. The holdover point is then illuminated inside your scope reticle for further precision.

The Sierra3BDX 4.5-14x50mm riflescope paired with the Kilo1000 BDX LRF offers exclusive elements such as the LevelPlex anti-cant system, so you can remain confident your optic is level for further in-scope adjustments. The optic also comes with HD glass and a BDX-R1 Digital Ballistic Reticle, ensuring 1-MOA accuracy guaranteed when shooting out to 800 yards. The riflescope tube size is 30mm, and the adjustment value is 1/4 MOA. Additionally, the reticle is available in the second focal plane.
