The Trijicon ACOG 100549 Matte Black 4x32mm Illuminated Red Chevron .223/5.56 BDC Reticle is a compact, rugged rifle scope designed for fast target acquisition and precise engagement on AR-platform rifles. Featuring a 4x magnification and a 32mm objective, it delivers a bright, clear sight picture with a durable matte black finish to resist harsh field conditions. The illuminated Red Chevron .223 reticle provides quick holdover and ranging cues, while the BDC design is calibrated for .223/5.56 ammunition to improve shot timing at mid-range distances. Built with the Colt Thumbscrew Mount and a versatile 25-32mm objective pairing, this optic integrates smoothly with modern sporting rifles, enabling secure mounting and dependable repeatability. The ACOGs compact profile maintains a low, snag-free silhouette, and the Type 2 RMR compatibility expands sighting options for co-witnessing setups when a secondary red dot is advantageous. With standard reliability from Trijicon, this scope combines precise glass, robust construction, and user-friendly illumination to support hunting, precision plinking, or tactical training where rapid target transitioning and accurate distance assessment matter most.
