Building upon SIG SAUER S lineage of innovative hunting optics, the all-new WHISKEY4 lineup gives the modern hunter a broad spectrum of rugged 4:1 variable power riflescopes designed to outperform season after season. Delivering quick and intuitive adjustments with a removable magnification throw lever and locking zero-stop elevation turret, the WHISKEY4 negates the need for any guesswork when the adrenaline spikes. Capable of delivering a crystal-clear image, even at high magnification, the WHISKEY4 lineup includes front and second focal plane configurations with SIG s illuminated Hellfire reticle in select models. In addition to the waterproof and fog-proof performance provided by Argon gas-purged lenses, each WHISKEY4 riflescope comes with factory-installed flip-back lens covers that maintain accessibility while keeping your optic protected.
