Designed for the AR and MSR (Modular Sniper Rifle), the Sig Sauer 5-25x52 WHISKEY5 Riflescope combines outstanding optics and a powerful 5:1 zoom mechanism with a partially illuminated reticle and precision turret system to produce a scope that is ideally suited for long-range shooting and hunting from dawn to dusk.

A suite of optical technologies is brought to bear that are designed to complement each other and enhance your view. First is the use of the HDX optical system, which is composed of extra-low dispersion (ED) and high-transmittance (HT) glass, which minimizes optical distortion and light absorption to transmit bright and clear images. Next Sig employs ultra-wide broadband, anti-reflection SpectraCoat lens coatings, along with protective LenShield and LensArmor coatings. This combination of glass and lens coatings produces high-resolution and high-contrast views in all light conditions. The front of the objective has threads for filters—like polarizing or ND—to enhance the views, especially when operating in snowy conditions or on/near water.

The reticle, located on the second focal plane, features illuminated center hairs for improved visibility with nine selectable intensity levels from two dim settings that are night vision device (NVD) compatible all the way up to a bright setting that makes it clear and distinct in full daylight. A motion detection system, MOTAC, automatically activates the illuminated portion of the reticle when the weapon is shouldered and powers it down when it senses inactivity after 2 minutes—providing instant illumination when you need it while ensuring a long battery life. Exposed tactical turrets provide a precise 0.1 MRAD per click impact point correction with 14 MRAD adjustment range on both the windage and elevation. To further improve accuracy, a free elevation Sig Ballistic Turret (SBT) is included with the scope. Simply fill out the form that comes with the scope and you'll receive a custom turret that is matched to your rifle and load and provides the correct ballistic drop compensation (BDC) at any range. You get one free with your scope purchase and you can order others for different rifles at an additional cost.

To withstand the repeated recoil of regular use and to provide the adjustment room required for the windage and elevation turrets, the one-piece maintube is made of lightweight but strong aluminum and is robust at 30mm in diameter. The housing is sealed to an IPX7 rating for water and fogproof performance in the most adverse weather, so the scope will keep working in the most extreme conditions.

Optical Performance

  • 5:1 zoom magnification range and large objective lens size are optimized for long-distance hunting and shooting
  • Powerful 5-25x magnification range allows the user to scan the landscape for targets on low power with the ability to zoom in and make detailed observations and identification at long ranges
  • Large 52mm objective lens gathers the light required for extended use in low and challenging light and to ensure views remain bright and clear when observing targets at long range on high magnification
  • Extra-low dispersion (ED) and high-transmittance (HT) glass provides enhanced light transmission to produce bright and clear high-contrast views with accurate color
  • Highly efficient, ultra-wide broadband, anti-reflection SpectraCoat lens coatings reduce surface reflections across the entire visible spectrum, improving light transmission
  • Extremely durable and abrasion-resistant LensArmor lens coatings ensure the lenses avoid scratches and other abrasions that can interfere with clear views
  • LenShield coatings repel water, grease, skin oils, and lens surface contaminants that can impair view clarity
  • 20-foot field of view at 100 yards on 5x power, 4-foot on 25x

MRAD Milling Hunter Reticle Details

  • Second focal plane placement: Reticle appearance won't change as magnification moves power up and down; it appears the same at all power settings
  • Partial illumination improves visibility of key parts of the reticle to improve accuracy in all light conditions
  • MRAD-based modified crosshair configuration specifically designed for mid- to long-range tactical engagements and hunting
  • Simplified design with long crosshairs presents an uncluttered field of view
  • Non-illuminated outer posts with illuminated thin center hairs
  • Illuminated hairs offer improved visibility in challenging light
  • Hash marks on all crosshair axes assist in estimating range to and size of target, ballistic drop compensation (BDC), hold-over/under, and to give lead to moving targets
  • Seven daytime and two night vision device (NVD)-compatible settings
  • Runs on one included CR2032 battery


  • Exposed finger-adjustable tactical turrets enable fast and fine adjustments in the field
  • Precise 0.1 MRAD per click impact point correction
  • 14 MRAD windage and elevation adjustment range
  • TH100 turrets have 100 clicks (10 MRAD) of travel per rotation on both windage and elevation
  • LockDown Zero System on turrets: A stop-locking turret that allows a rapid return to zero that also locks at zero
  • Combination illumination control and parallax adjustment turret
  • Free elevation Sig Ballistic Turret (SBT) that is matched to the user's rifle/load and allows for correct BDC at any range; one free with purchase, others are available at additional cost

Use and Handling

  • LevelPlex digital anti-cant system utilizes an integrated digital level with indicators to enable the user to precisely optically align the scope to their rifle and remove unwanted cant from the system to ±0.5° of accuracy—ensuring the horizontal and vertical axes of the reticle are perfectly parallel to the rifle
  • Fast-focus eyepiece
  • MOTAC motion sensor system immediately powers up illumination when it senses motion and powers down when it does not detect movement for 2 minutes in order to extend battery life
  • M54x0.75 objective filter thread allows the use of front filters, like polarizing or neutral density, to enhance the view
  • Long 3.8" eye relief provides a generous eye box to improve comfort and reduce eyestrain
  • Comfortable exit pupil at low and medium magnifications provides easy use in low or challenging light

Construction Details

  • Sturdy 30mm maintube maximizes light throughput to the user's eye and provides the room required for greater windage and elevation adjustment range
  • Lightweight and durable aluminum housing
  • General-purpose reflection-limiting matte black anodized finish
  • IPX7-rated to be waterproof and submersible to 3.3 feet for up to 20 minutes, as well as fogproof
  • Length: 13.5"
  • Weight: 28.8 ounces
