The SIG Sauer SIERRA6BDX 5-30x56 Rifle Scope is a premium long-range hunting and precision rifle scope built around SIG's BDX Ballistic Data Xchange technology. Paired with a compatible SIG BDX rangefinder, the BDX-R2 digital reticle lights an intelligent holdover dot based on range, ballistics and environment for confident shots at distance.
A high 5-30x zoom, large 56mm objective and 34mm tube (for extra adjustment range) are matched to the HDX 6x optical system with up to 95% light transmission. LevelPlex anti-cant, KinETHIC energy indicator and adjustable parallax complete a serious long-range package.

Frequently Asked Questions
What is BDX?
SIG's Ballistic Data Xchange — paired with a compatible SIG BDX rangefinder, the scope automatically displays an illuminated holdover dot for the ranged distance.
Does it work without a rangefinder?
Yes — it works as a standard illuminated scope, but the auto-holdover feature needs a compatible BDX rangefinder.
What mount does it need?
A 34mm mount or rings — see our rifle scope mounts.
