The Sightron S-TAC 4-20x50 rifle scope delivers versatile long-range performance with a 30mm main tube, a 4-20x magnification range, and a 50mm objective that yields bright, sharp imagery on demanding hunts and precision rifle tasks, while the second focal plane ensures your holdovers remain consistent as you zoom. Its 23.6-4.4 feet of field of view at 100 yards, side focus parallax adjustment from 10 yards to infinity, and generous 3.7-4.0 inches of eye relief combine for rapid target acquisition and reliable eye-box comfort, even in dynamic field conditions. The duplex reticle paired with 1/4 MOA click values and 15 MOA per revolution delivers precise, repeatable elevation and windage corrections, aided by 40/80 MOA total travel for substantial dialing capability, though with a nonzero stop design. Built to endure with matte black finish, waterproof construction, and full multi-coating (Zact-7), it remains sharp in rain or mud, while a sturdy 14.8-inch length and 23.6-ounce weight keep balance on practical hunting rigs. This scope, optimized for rifle use, excels in varmint and big-game scenarios, delivering reliable performance across a broad range of field conditions.
