The Elcan SpecterDR DFOV4-B146-C10-SAI3 is a professional dual-role combat optic that instantly switches between 1x CQB and 4x medium-range magnification via an ambidextrous throw lever, maintaining identical 70mm eye relief in both modes. The 2024 model features a Cerakote black finish, integrated Picatinny rails, and a 32mm objective lens with an 8mm exit pupil for strong low-light performance. The CX5395 BDC reticle is calibrated for 5.56x45mm NATO M855 from a 16-inch M4 barrel, with five LED brightness settings including two night-vision compatible modes. Turrets adjust in 0.5 MOA increments over a ±60 MOA range and the optic mounts to any MIL-STD-1913 rail via the included A. R.M. S. MK-II throw lever mount. Rated waterproof to 66 feet and shockproof to 450 G's, the SpecterDR weighs 640g in a compact 153mm package.
