Sig Sauer SIERRA4 BDX 6-24x50mm 30mm Digital Scope

The Sig Sauer SIERRA4-BDX is a digital ballistic riflescope designed to pair with BDX-enabled rangefinders and deliver an illuminated, data-driven holdover dot specific to range and environmental inputs. It uses a digital focal plane reticle to present moveable LED hold points and supports up to 194 individually controlled LEDs. The scope provides a wide 6-24x magnification range with a 50mm objective and a 30mm main tube for a balance of magnification and optical performance.
