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, this sight is 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 pair with a standard front sight tower or Daniel Defense's rail-mounted fixed front sight, this rear sight provides a clean fixed-iron backup for AR-platform rifles. 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 rear delivers the reliability that professionals demand.
