The Holosun Absolute Co-Witness Picatinny mount for 503 and 403 series optics (part no. AACW1.4) provides a sturdy, reliable base for these red dot sights in both tactical and range environments. Holosun constructs the mount from high-strength aluminum with a hard-anodized, corrosion-resistant finish built for durability and longevity. The riser positions the optic at a total height of 1.4 inches from the Picatinny rail, allowing absolute co-witness with iron sights for precise target acquisition. Compatible with standard Picatinny rail systems, this mount suits AR-15 rifles and other firearms that need a secure, stable optic mounting solution. Among co-witness scope accessories, this mount favors shooters running Holosun 503 or 403 series sights who want iron-sight backup.
