Sig Sauer Sierra3 BDX 4.5-14x50mm 30mm | SOSBDX34112

The SIG SAUER Sierra3 BDX is a digital-enabled riflescope that integrates SpectraCoat optics with the BDX Ballistic Data Xchange system to provide automatic ballistic holdover when paired with a BDX-capable rangefinder. It uses an illuminated BDX-R1 reticle on a second focal plane and a 30mm main tube for a balance of elevation adjustment and rigidity. The scope includes LevelPlex digital anti-cant and KinETHIC kinetic energy transfer indication to assist ethical shot decisions. Optical and electronic systems are sealed for reliable, weather-resistant performance in field conditions.
