Fits Aimpoint M68 Close Combat Optic and most other Aimpoint sight models. The KillFlash anti-reflection device is designed to eliminate potentially compromising reflections from the objective lens. This rugged, low profile KillFlash™ ARD enhances the close combat optics use under a wide range of infantry engagement scenarios, including patrolling, MOUT, close quarters battle (CQB), and fire and maneuver operations. The patented geometry of the CC-As honeycomb shield maintains a clear, bright view through the sight and does not interfere with target acquisition. The lightweight, low maintenance design of the CC-A adds virtually no additional weight to the soldiers load and provides essential objective lens protection against the elements and rough handling. Simple screw-in installation allows the sight's existing flip-open cover to still be used.
