Sig Sauer Electro-Optics Sow42003 Whiskey4 Black 2.50-10X 42Mm 30Mm Tube Quadplex Reticle

The Sig Sauer Whiskey4 2.5-10x42mm rifle scope brings versatile variable magnification and rugged reliability to hunters and precision shooters who demand glass they can trust across multiple seasons and conditions. This 30mm tube scope features a second focal plane Quadplex reticle designed for quick target acquisition and intuitive holdover in the field. Built with nitrogen-purged lenses for waterproof and fog-proof performance, the Whiskey4 delivers a crisp, clear sight picture whether you're glassing at low power for a wide field of view or cranking up to 10x for precise long-distance assessment.

What sets the Whiskey4 apart is its thoughtful ergonomic design: a removable magnification throw lever gives you fast, intuitive power changes without fumbling, while factory-installed flip-back lens covers keep your objective and eyepiece protected without compromising quick access. The scope's mechanical simplicity—precise 1/4 MOA elevation and windage adjustments with solid travel (80 MOA elevation, 52 MOA windage per rotation)—means reliable performance in the field with zero dependency on batteries. Variable parallax adjustment lets you dial in the sight picture for your distance, while generous eye relief (3.7–4.0 inches) accommodates most shooting positions comfortably.

Hunters who've relied on Sig Sauer optics for years know the company builds glass that handles the unexpected. The Whiskey4 lineup continues that tradition: it's rugged enough for backcountry hunts and precise enough for mid-range shooting. At 22.3 ounces, it won't burden your rifle. This scope does not include a mount—you'll need to source one separately based on your rifle's platform.

Frequently Asked Questions

What's the difference between the Whiskey4 and other variable power hunting scopes?

The Whiskey4 combines Sig Sauer's proven optical design with hunter-focused features like the removable throw lever and flip-back lens covers. The 2.5-10x magnification range balances wide-field scanning at low power with effective long-range capability, making it adaptable across most North American hunting scenarios. The second focal plane Quadplex reticle is straightforward and uncluttered—no complicated subtensions to manage in the moment.

Does this scope require a battery or illuminated reticle?

No. The Whiskey4 with the Quadplex reticle is a non-illuminated, all-mechanical scope. There's no battery to maintain, and no electronics to fail in the field. That reliability is often preferred by hunters who want one less variable to worry about.

What mount does the Whiskey4 use, and is one included?

The scope features a 30mm tube, which is compatible with standard 30mm ring systems. No mount is included with this scope—you'll need to purchase one separately based on your rifle's platform and preferred mounting method.

Is the Whiskey4 weatherproof for hunting in rain or snow?

Yes. The scope is nitrogen-purged, waterproof, and fog-proof, so it will handle wet conditions and temperature swings typical of hunting seasons. The flip-back lens covers also protect the objective and eyepiece when the scope isn't in use.
