Daniel Defense A1.5 Fixed Rear Sight

The Daniel Defense A1.5 Fixed Rear Sight brings the reliability and proven design of traditional AR iron sights to modern Picatinny rail platforms. Machined from 6061-T6 aluminum and finished with Type III hard anodizing, these sights are built to withstand the rigors of professional use while maintaining zero through thousands of rounds and hard handling.

The A1.5 designation refers to the hybrid design that combines the best features of the A1 and A2 sight configurations. The dual aperture design provides both a small precision aperture for deliberate shooting and a larger aperture for rapid target acquisition in close quarters or low light conditions. The precision windage adjustment turret clicks positively and holds zero through extreme conditions.

Designed to work as a complete system with the matching Daniel Defense fixed front sight post, these sights provide the ultimate backup sighting solution for any AR-platform rifle. The low-profile design sits close to the receiver, minimizing snag points while providing a proper sight picture. Whether used as primary irons or backup to a red dot optic, the DD A1.5 sights deliver the reliability that professionals demand.
