Dirty Civilian compares the replicas of some of the real world optics makers, using on them to shoot with real steel in this episode... "We tested Airsoft knockoff optics on real firearms and compared them to real optics from Trijicon, Aimpoint, EOTech, and SIG Sauer. The goal was simple: can clone red dots and holographic sights be zeroed and used reliably on rifles and pistols? The results surprised us in both good and bad ways.
