The Elcan SpecterDR 1x/4x Dual Role Weapon Sight is a highly versatile, combat-proven optical system optimized for both close-quarters room clearing and mid-range precision targeting. Featuring an external mechanical throw lever, operators can immediately toggle between a true 1x unmagnified field of view and a 4x magnified setting without losing their cheek weld or changing target alignment. This specific configuration features the CX5395 ballistic reticle, precisely calibrated for the trajectory of 5.56x45mm NATO M855 (62-grain) ammunition fired from a standard 16-inch M4 barrel platform. As a comprehensive factory demo unit, it comes outfitted with premium tactical upgrades including impact-resistant flip-up lens covers and a signature honeycomb anti-reflection device (ARD) kill-flash insert. The entire assembly sits on an integrated base secured by heavy-duty dual A. R.M. S. quick-detach throw levers, guaranteeing flawless return-to-zero tracking when mounted to any standard Mil-Std-1913 Picatinny rail.
