Specially calibrated for .223, the Core HX 3-12X56 AR-223 riflescope offered by Sightmark sets the standard when you want to shoot at short distances. This scope is ideal for tactical operations, competitions, and shooting. It has a length of 330 mm, and the central tube has a diameter of 30 mm. The internal objective has an inner diameter of 24mm, allowing for good image clarity.

The construction of matte black anodized aluminum with multi-coated glass offers the same quality and performance that Sightmark is known for. Ready to withstand extreme conditions, the Sightmark scope is waterproof, fog-proof, dust-proof, and shockproof.

The scope features variable zoom from 3x to 12x and is equipped with HDR (Hunter Dor Riflescope) to help compensate for bullet trajectory (or any other projectile) by providing marked ballistic circles, making it easy to determine the holding position for distant targets.

The reticle is illuminated in red or green and is powered by a CR2032 3V battery located in the same turret that integrates the brightness adjustment dial. The battery life varies between 70 and 100 hours of continuous operation, depending on the selected brightness level.
