The Aimpoint CEU™ (Concealed Engagement Unit) is the latest component incorporated into Aimpoint’s unique System-of-Systems™ approach. It gives the operator the ability to observe and/or engage a threat from a concealed or covered position. The Aimpoint CEU easily rotates from side to side, so an operator can safely look around either right- or left-hand corners. It can also be quickly removed to rapidly return to direct engagement.
