Sig Sauer WHISKEY3 4-12x40 Riflescope, Black, Standard QuadPlex Reticle, 0.25 MOA Adjustment

The Sig Sauer WHISKEY3 4-12x40 riflescope is built for hunters and shooters who need reliable magnification across a range of shooting distances and platforms. Whether you're running it on a traditional hunting rifle, an AR platform, or anything in between, this scope delivers the optical performance and ruggedness expected from Sig Sauer, without unnecessary complexity or cost. The 4-12x magnification strikes a practical balance for short- to medium-range work, making it a solid choice for game hunting, recreational shooting, and general-purpose rifle optics across common calibers.

Optical clarity matters in the field, and the WHISKEY3 doesn't cut corners there. Low dispersion glass combined with SpectraCoat lens coatings work together to reduce glare and maximize light transmission in varied lighting conditions. The standard QuadPlex reticle is simple, time-proven, and intuitive—no learning curve, just aim and shoot. Second focal plane design means the reticle stays a consistent size no matter your magnification setting, keeping holdovers straightforward.

Construction is fieldworthy: a 1-inch tube diameter fits most standard rings and mounts, fog-proof and waterproof sealing protects against weather and rough handling, and the European-style eyepiece allows smooth, precise turret adjustments in 0.25 MOA increments. At 12.4 inches long and 16.6 ounces, the scope stays lightweight and balances well on most rifles. The 3.6-inch eye relief provides good breathing room behind the gun, and the 100-yard parallax adjustment keeps images sharp across typical hunting and target ranges.

This is a no-fuss riflescope for people who value solid optics and honest performance. It won't dazzle you with gadgetry, but it will hold zero and let you see your target clearly, day after day.

Frequently Asked Questions

Will the WHISKEY3 4-12x40 work on both AR platforms and traditional hunting rifles?

Yes. The 1-inch tube diameter and standard mounting interface make it compatible with most modern hunting rifles and AR-style platforms. It's designed to work across a wide range of rifle types and calibers.

What does second focal plane mean, and does it affect how I use the reticle?

In second focal plane (SFP), the reticle size remains visually consistent regardless of magnification. This means holdovers and windage calls don't change as you adjust power—what you see at 4x matches what you see at 12x. It's the traditional design most shooters are familiar with, and it keeps things straightforward in the field.

Is the WHISKEY3 waterproof and fogproof?

Yes. The scope is sealed and treated to be both waterproof and fogproof, protecting internal optics from moisture and condensation during wet weather and temperature swings.

What's the difference between the SpectraCoat lens coating and standard coatings?

SpectraCoat is Sig Sauer's multi-coated lens treatment designed to maximize light transmission and reduce internal glare, resulting in brighter, clearer images with better contrast in varying light conditions.
