This Elcan SpecterDR scope is a high performance switchable 1-4x dual-field-of-view combat optic with clip-on night vision capabilities. Switching between sights leaves the US Special Operations and Navy Seals vulnerable, which is why they choose the Elcan SpecterDR. Includes A. R.M. S. Picatinny Mount. The Elcan SpecterDR Tactical Rifle Scope is a revolutionary optical sight design in the scope industry. The Elcan SpecterDR is the world's first truly dual field of view combat optical sight that combines the best of close and precision fire ranged combat features. The SpecterDR can switch instantly from a 4x magnification to a 1x CBQ with the throw of a lever. The SpecterDR offers the same eye relief in both 4x and 1x modes. What separates the SpecterDR is that it is half the weight and twice the capability and carrying two scopes, without compromise to mission effectiveness or reliability.
