The image displayed on the scope isn’t a direct visual, but rather a video image taken through the scope’s objective lens. 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.

Linux in a high-powered hunting rifle. I’m pretty sure this is how every robot apocalypse movie ever made begins.
