Sightmark Core TX AR-223 4x24mm BDC Riflescope

The Sightmark Core TX AR-223 is a 4x24mm riflescope with a 30mm tube, specifically calibrated for .223 ammunition. It delivers a field of view ranging from 96.1 feet at 4x magnification down to 24.1 feet at the widest setting, measured at 100 yards. Eye relief runs 4 to 3.47 inches depending on magnification. The second focal plane reticle features red and green illumination, while exposed pop-up locking turrets allow for precise windage and elevation adjustments. A 24mm objective lens with fully coated optics delivers a bright image, and the aluminum construction is sealed to remain waterproof, shockproof, and fogproof in the field. At 9.64 inches in overall length, it’s built to mount on modern AR platforms and similar short-action rifle systems.
