A class-action lawsuit accused L-3 Communications and its EOTech subsidiary of selling consumers defective combat optical sights. The lawsuit alleged L-3 knew and failed to warn consumers that the sights contained defects that caused them to fail to perform as warranted in cold temperatures and humid environments. In July 2017, L-3 agreed to pay $61 million to settle the lawsuit. Two years earlier, L-3 and EOTech paid the federal government $25.6 million and admitted to concealing the defect from government purchasers for several years (see L-3 Communications instance, “U.S. v. L-3 Communications EOTech (Defective Weapons Sights)”).
