What you're looking at is basically a .338 Lapua Magnum rifle that's been equipped with a Linux-powered TrackingPoint XS1 system, an advanced computerized scope, that guarantees a perfect shot everytime, thanks to an auto-aim function once the target is marked. Continue reading for a video and more information.
Here's how it works: "The Linux-powered scope produces a display that looks something like the heads-up display you'd see sitting in the cockpit of a fighter jet, showing the weapon's compass orientation, cant, and incline. To shoot at something, you first "mark" it using a button near the trigger. Marking a target illuminates it with the tracking scope's built-in laser, and the target gains a pip in the scope's display. When a target is marked, the tracking scope takes into account the range of the target, the ambient temperature and humidity, the age of the barrel, and a whole boatload of other parameters. It quickly reorients the display so the crosshairs in the center accurately show where the round will go."
