The official spotting scope of the U.S. Army’s new XM110 Semi-Automatic Sniper System (SASS), the Mark 4 12-40x60mm Tactical spotting scope is ideally suited for use as part of a shooting team. It features either a Mil Dot or Tactial Milling Reticle, and you can outfit it with a variety of performance-enhancing accessories. Powerful, with bright, clear optics, it’s also supremely rugged and waterproof. It’s for all these reasons that the Mark 4 spotting scope is highly prized by hunters and shooters everywhere, as well.
