Specifically designed by ELCAN for the U.S. Army and other elite fighting teams for application to Machine Guns, M4 Carbines, M16/AR15 and AR10 rifles. The SpecterM145 is the U.S. government model (NSN 1240-01-411-6350) of the ELCAN 3.4x magnification optical rifle sight employed as the standard machine gun optical sight (MGO). The front objective is fitted with a laser filter and Signature Reduction Device. The 10m-1200m ranging reticule is illuminated by a rotary switch (11 levels plus an off switch). The standard weaver with cross-slots rail mount (Picatinny) attaches quickly to any MIL-STD-1913 receiver or base in seconds with a single torque-limited knob and provides all windage and elevation zeroing corrections. The sight retains zero when removed and reattached to the weapon. Rear and front lens covers flip down for storage and transportation.

SpecterM145 has proven its effectiveness on a variety of high-powered rifles and machine guns, permitting tracer rounds and fall of shot to be clearly seen at extended ranges.
