Sightron S-TAC 4-20×50 Second Focal Plane Rifle Scope – Duplex Reticle, 30mm Tube, Side Focus

The Sightron S-TAC 4-20×50 is a precision-built rifle scope engineered for competitive shooters, long-range hunters, and tactical marksmen who demand reliable optical performance without breaking the bank. Featuring a versatile 4-20x magnification range paired with a 50mm objective lens, this scope delivers a wide field of view of 23.6 ft at 100 yards at low power, narrowing to 4.4 ft at full magnification — giving you the flexibility to engage targets at virtually any distance.

The second focal plane (SFP) design keeps your Duplex reticle at a consistent size throughout the magnification range, making it ideal for precise aiming at a fixed power setting. Resettable target-style turrets with 1/4 MOA click values and 15 MOA per revolution provide repeatable, tactile adjustments, while the generous 40 MOA windage and 80 MOA elevation travel accommodates long-range corrections with ease.

Sightron’s proprietary Zact-7™ 7-layer fully multi-coated optics maximize light transmission for bright, sharp, and high-contrast images even in challenging lighting conditions. The side-focus parallax adjustment — ranging from 10 yards to infinity — ensures a crystal-clear, parallax-free sight picture across the full distance spectrum.

Built on a robust 30mm main tube in a matte black finish, this scope is fully waterproof and fog-proof, ready to perform in any environment. At 14.8 inches long and 23.6 oz, it strikes a practical balance between durability and packability.
