Sightron's newest addition to its SII Big Sky line is a 36X 42mm scope built around a one-piece mono-tube with precision-ground and hand-fitted lenses, the outside surfaces of which are coated with Zact-7 multi-layer coating. The SII Big Sky 36X 42mm scope uses the ExacTrack adjustment system with 1/8-MOA target knobs. By loosening three setscrews on the turret, the scope can be reset to zero.

The scope also incorporates a 1/8-MOA dot reticle. This scope has an adjustable objective and a long eye relief of 3.7 inches, and focus goes as close as 10 yards. It comes with Sightron's Lifetime Replacement Warranty.
