SIGHTRON SCOPE S-TAC 4-20X50 – DUPLEX TARGET KNOBS 30MM SF

Target shooting at distance requires optics built for precision adjustment and clarity across extended magnification ranges. The 4-20x50 configuration delivers the flexibility competitive shooters and long-range hunters need, whether you're zeroing at 100 yards near Vacaville or dialing in at 600+. TacticCAL handles FFL transfer in Sunnyvale for shipped scopes and serves the Bay Area with inventory ready to mount.

Duplex reticle with turret-mounted adjustment

The Duplex pattern provides the contrast most shooters prefer for quick target acquisition without introducing visual clutter at high magnification. Target knobs let you dial elevation and windage with tactile feedback—critical when conditions shift mid-session. The 30mm tube maximizes light transmission through the 50mm objective. Adjustable parallax keeps the reticle locked to your point of aim across the full 4-20x zoom range. Whether you're handling legacy firearms or exploring PC §32100 exempt revolvers, reliable glass matters. Visit our gun store in Sunnyvale for our full catalog.

Frequently asked questions

What's the practical eye relief on this 4-20x magnification scope?

Sightron S-TAC models typically deliver 3.5 inches of eye relief across the magnification range. This distance remains consistent enough for field use, though higher power requires more precise head positioning.

Does the adjustable parallax dial work smoothly at 20x magnification?

Yes. The parallax adjustment is engineered to eliminate image shift across the full zoom range. At 20x, dialing parallax ensures target clarity without introducing reticle movement—essential for precision work.

Yes — TacticCAL processes ammunition shipments from online sellers under California's ammunition eligibility check requirements. TacticCAL is your gun shop Berkeley in the Bay Area.
