SIG BDX Scopes
The SIG BDX riflescope lights a holdover when it pairs with a KILO BDX rangefinder. SIERRA6-BDX is the HDX hunting scope with a BDX-R2 digital ballistic reticle, KinETHIC, and LevelPlex: 2-12×40 and 3-18×44 on a 30 mm tube, 5-30×56 on a 34 mm tube. SIERRA4-BDX is 4-16×44 and 6-24×50 with BDX-R2. SIERRA3-BDX is 3.5-10×42 and 4.5-14×50 with BDX-R1. Those SIERRA scopes are second focal plane.
BRAVO6T-BDX is the first-focal-plane HDX tactical scope with eTRAK, ZeroSync, and an ALPHA5 mount with an LRF diving board in the box. Reticles are MRAD DEV-L 2.0 or MRAD Milling 2.0 at 3-18×44 and 5-30×56. EASY6-BDX is the BDX LPVO at 1-6×24 with BDX-R2, plus 3-18×44 and 5-30×56 with Digital DEV-L. Pairing is not universal. See also SIG KILO rangefinders.

A BDX riflescope lights a holdover when it pairs with a compatible KILO BDX rangefinder. Pairing is not universal.
What is the difference between BDX-R1 and BDX-R2?
SIERRA3-BDX uses BDX-R1. SIERRA6-BDX, SIERRA4-BDX, and the EASY6-BDX 1-6×24 use BDX-R2.
Does BRAVO6T-BDX include a mount?
Yes. The BRAVO6T-BDX kit includes an ALPHA5 1.250 in. mount and an LRF diving board. SIERRA and EASY6 scopes do not include a mount.
Do I need a KILO rangefinder?
The scope works as a riflescope on its own. The illuminated BDX holdover needs a compatible KILO BDX rangefinder. That rangefinder is sold separately.

It is SIG’s 30 mm LPVO with a BDX-R2 digital ballistic reticle. The 3-18×44 and 5-30×56 EASY6-BDX scopes use Digital DEV-L instead.
