Aimpoint started out as a Hunting "Red Dot Optic" and evolved into a multi million $$$$$ company with contracts from the Military. Aimpoint is one of the most used Red Optics for military use.
Origin: Aimpoint's story traces back to an unlikely source—a toilet roll! In 1974, technician and inventor Arne Ekstrand wanted to improve his accuracy while hunting and on the shooting range. He noticed that the light reflection on the wall behind him remained steady, regardless of his head movements. Inspired by this observation, he sketched a concept for a red dot sight based on an empty toilet roll.
