Sig Sauer Whiskey 4 5-20x50 FFP Illuminated MOA HNT 2.0 Rifle Scope

The Sig Sauer Whiskey 4 5-20x50 FFP illuminated MOA rifle scope is built for the modern hunter who demands precision without compromise. This first focal plane scope delivers a 5-20x magnification range in a rugged 30mm tube, engineered to stay crystal-clear even when cranked to maximum power. The front focal plane design means your MOA Milling Hunter 2.0 reticle stays true at any magnification—critical for range estimation and holdover calculations from the stand or across open country. Whether you're glassing at first light or making a long-distance shot, the Whiskey 4 combines tactical-grade performance with hunting-friendly ergonomics.

Setup and field adjustments happen fast with a removable magnification throw lever and a locking zero-stop elevation turret—no second-guessing your zero when adrenaline runs high. Each click is a precise 1/4 MOA, with over 52 MOA of total elevation and windage travel to handle steep angles and extreme distances. The illuminated reticle (powered by a single CR2032 battery) lights up in low-light conditions, and Sig's MOA Milling Hunter 2.0 pattern gives you holdover points for quick shooting without the math.

Durability is non-negotiable. Argon gas purging keeps the optic waterproof (IPX 6 rated) and fog-proof through temperature swings and weather abuse, while factory-installed flip-back caps protect your objective and eyepiece without slowing you down. At 22.6 ounces, it balances serious glass with rifle weight discipline. Eye relief ranges from 3.9 inches at low power to 3.5 inches at high magnification, and a ±2 diopter adjustment lets you dial focus to your eye.

The 50mm objective and high-end optics deliver a bright, detailed sight picture whether you're hunting timber or open slopes. Field of view sweeps from 18 feet at 5x down to 4.5 feet at 20x—wide enough for tracking movement, tight enough for precision aiming.

Frequently Asked Questions

Is this scope first focal plane or second focal plane?

This is a front focal plane (FFP) scope. The reticle stays proportional to your point of impact at any magnification, which means your MOA holdovers and windage corrections stay accurate whether you're at 5x or 20x—a big advantage for precise, long-range shooting.

What reticle does the Whiskey 4 have?

The scope features a MOA Milling Hunter 2.0 reticle with illumination. The pattern includes holdover points for range estimation and leads for moving targets, and the illuminated center lights up in dim conditions via a CR2032 battery.

How much elevation and windage adjustment does this scope have?

You get over 52 MOA of travel in both elevation and windage. The locking zero-stop elevation turret prevents accidental rotation, and each click is 1/4 MOA for precise dialing at distance.

What's included with the Whiskey 4 scope?

The scope comes with removable flip-back lens caps and a removable magnification throw lever. It's factory-ready to mount on a 30mm ring system.
