Sightron S-TAC 4-20x50 Duplex 30mm Tube Side Focus Riflescope - Target Knobs

The Sightron S-TAC 4-20x50 is a versatile variable-power riflescope engineered for target, varmint, and hunting applications. With a 5x zoom factor and a large 50mm objective lens, this scope transitions smoothly between mid-range and long-range engagements while gathering ample light for a bright, crisp sight picture.

At the core of the S-TAC is a rugged 30mm one-piece main tube that maximizes durability and internal adjustment travel. The Duplex reticle is illuminated with 11 brightness settings, powered by a readily available CR2032 battery, giving shooters a clear, adjustable aiming point in nearly any lighting condition from dawn to dusk.

Practical field features include a fast focus eyebell for quick diopter adjustments, resettable low-profile target knobs with 1/4 MOA per click adjustments for dialing precise corrections, and a side focus parallax system that adjusts from 9 yards to infinity to eliminate parallax error across the magnification range. The scope measures 14.8 inches long, weighs 23.6 oz, and is finished in non-reflective matte black. It is fully waterproof for dependable performance in adverse weather.

Built around a side focus design with target-style resettable turrets and an illuminated Duplex reticle, the Sightron S-TAC 4-20x50 gives precision shooters a flexible optic platform for serious work at the range or in the field.
