Trijicon TA31-C-100550 ACOG 4x32mm .223 BDC with RMR

The Trijicon TA31-C-100550 combines a 4x32mm ACOG scope with an illuminated red .223 BDC crosshair reticle and a Trijicon RMR Type 2. The optic uses fiber optics and tritium for dual illumination, while the included TA51 mount supports installation on a flattop platform.

The ACOG reticle is calibrated for .223 and provides bullet drop compensation to 600 meters without manual reticle adjustments. The top-mounted RMR Type 2 provides a 3.25 MOA red aiming dot for an alternate sighting option.
