For hunters who want a very clear, crisp image, even out beyond 400 yards, consider a European brand with best-in-class optics. If you’re looking for a model that combines excellent optical glass, versatile crosshairs, positive turret movements, and useful illumination modules, look to the European brands such as Zeiss, Kahles, and Leica. But if you want decent glass and battle-proven controls plus an ironclad fully transferrable warranty, look to American brands such as Nightforce, Vortex, and Leupold.
