#223 Ivory Mid-rib Sight

The #223 Ivory Mid-rib Sight by Marble Arms is a precision open sight designed for shooters who demand reliable, fixed-position aiming on rifles chambered in .223 Remington and 5.56 NATO. This sight fills a critical role in the field: providing a durable backup aiming solution when mounted to the flat-top receiver rail of modern tactical platforms. Whether deployed by law enforcement, military personnel, or serious civilian marksmen, the ivory bead front sight delivers fast target acquisition in daylight conditions without battery dependency or electronic failure modes.

Built with Marble Arms' reputation for manufacturing robustness, the #223 Ivory Mid-rib Sight features a bright ivory bead front element positioned on a mid-rib ramp design that reduces glint and provides an optimal sight picture for 5.56/.223 ballistics. The mid-rib configuration elevates the sight post above standard gas tube height, allowing unobstructed view through co-mounted optics while maintaining rapid-access capability if primary glass fails. The sight's fixed geometry is optimized for typical 50–300 meter combat ranges, and the ivory bead stands out in both low and bright light without requiring protective coatings that degrade over time.

This sight integrates seamlessly with any flat-top AR platform using standard Picatinny rail mounting, making it compatible with virtually all modern .223/5.56 tactical rifles and carbines. Weighing only 0.01 lbs, it introduces negligible mass while delivering battlefield-proven reliability. Operators favor the #223 Ivory Mid-rib Sight as a lightweight, maintenance-free insurance policy—eliminating the single point of failure risk inherent to magnified optics-only setups. Installation requires no gunsmithing, and the sight's compact profile ensures zero interference with popular sight packages, tactical lights, or foregrips.
