CounterSniper Optics rifle scopes are built for professionals of all stripes, from law enforcement to military to competition shooters. These state of the art riflescopes were born from a decade of development for the sterile and untraceable optical rifle sighting requirements of Special Operations and clandestine warfare, so you know you're getting technology that is light, tough, and above all, accurate. Each riflescope by CounterSniper is built with highly durable materials (titanium or T6061 aluminum), feature extra low dispersion glass, and utilizes highly efficient tactical style locking turrets. Counter Sniper Military Optical Gunsights Corp finishes all their scopes with a proprietary rare earth/nitrogen/argon gas purging that makes them effectively waterproof and fog proof for high clarity performance on every shot. For a scope that won't let you down in the most demanding tactical or outdoor situation, choose one of the many Counter-Sniper Optical riflescopes.
