The Sig Sauer Sierra3 BDX Optics System, as explained by Pete Howell from Sig Sauer and Steve from Brownells, integrates a BDX rangefinder with a Sierra3 scope for automated ballistic solutions.

Once configured, the system provides an illuminated hold point directly in the reticle, allowing shooters to extend their effective range with increased confidence.
