Designed for use at all distances from the first light through to late dusk—and optimized for the AR and MSR (Modular Sniper Rifle)—the Sig Sauer 3-9x50 WHISKEY3 Riflescope gives you a flexible and reliable optic that is enhanced with the addition of the HellFire illumination system, which makes the center aiming point easy to see in all light conditions.

The WHISKEY3 is outfitted with a second focal plane partially illuminated reticle that features Sig's fiberoptic HellFire illumination system, which offers selectable intensity levels from dim settings that are night vision (NVD) compatible all the way up to a bright setting that makes the center aiming dot clearly and distinctly visible. Complementing the magnification range and reticle design are capped low-profile windage and elevation turrets that adjust as much as 80 MOA at 1/4 MOA per click increments to improve your first-shot accuracy.

Optically, Sig employs a large 50mm objective lens that gathers copious amounts of light that ensures views remain bright and clear in low light or if you are observing targets at long range on high power. The scope utilizes low-dispersion glass that corrects spherical and chromatic aberrations, so views are clear and undistorted with accurate color and improved contrast and clarity. Ultra-wide broadband anti-reflection SpectraCoat lens coatings further improve light transmission across the entire visible spectrum, while LensArmor coatings provide resistance to scratches and abrasions to ensure views remain crisp and clear. The 1" maintube is made of a light and durable aluminum alloy treated with an anodized finish for durability and longevity. To withstand the harsh elements of the trail, the housing is nitrogen filled and O-ring sealed to an IPX7 rating to make it waterproof, submersible, and resistant to internal fogging.

Optical Performance

  • 3:1 zoom magnification range and objective lens size are optimized for short-, mid-, and long-range shooting
  • Low 3-9x magnification allows the user to scan wide areas of the landscape with the ability to zoom in and make positive identification, with capability to take shots at longer distances if required
  • Large 50mm objective provides the light gathering required for extended use from the pre-dawn hours through into late dusk
  • Low-dispersion (LD) glass corrects aberrations, improving contrast and color fidelity and correcting lens-edge curvature
  • 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
  • 35-foot field of view on 3x, 12' on 9x

HellFire QuadPlex 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
  • Traditional duplex crosshair design
  • Center illuminated red dot provides a clear aiming point in all light conditions
  • Non-illuminated long outer posts draw the eye to the center aiming point on low power
  • Short center hairs provide precision aiming on high power without obscuring smaller targets
  • Clearly defined aiming at all magnifications
  • Proprietary HellFire illumination system utilizes fiberoptic technology to adjust the intensity of the center aiming point from dim IR compatible to a bright dot that can easily be seen in full daylight, resulting in a clearly defined aiming point in any light condition
  • Multiple brightness settings from dim night vision device (NVD) compatible to high intensity for bright daytime visibility
  • Runs on one included CR2032 battery

Use and Handling

  • Textured zoom and focus collars are easy to manipulate in cold and wet weather
  • Precise 1/4 MOA per click impact point correction
  • Wide 80 MOA windage and elevation adjustment range provides the room for longer-range use
  • Capped turrets ensure dirt and dust won't foul the adjustment mechanism; low-profile design reduces snag hazards
  • One custom SBT elevation turret dial, ordered and delivered directly from Sig, is included with purchase—others are available for order separately from Sig
  • 3.6" eye relief provides a generous eye box with improved comfort and mount placement flexibility
  • Ultra-wide exit pupil at all magnifications ensures the whole scene remains in view, even in extremely low or challenging light

With the hellfire option it is going to improve my limited eye sight. Wish it had shake awake feature

Why "No SBT"?

Why "No SBT"?
Asked by: GERALD
If you look the various reticles the No/SBT is just another choice you can make. If you want the HellFire QuadPlex Illuminated with SBT. All you have to do is select HellFire QuadPlex Illuminated and it will come with (SIG Ballistic Turret). If you don't want it then you would select HellFire QuadPlex Illuminated/No SBT. So you can have it or not depending on your selection.
