Kriss USA Defiance Rear Flip-Up Sight Steel Black Low Profile AR

The Kriss USA Defiance rear flip-up sight brings OEM-grade durability and minimal profile to your AR platform. Originally engineered for the KRISS Vector SMG, this rear sight collapses completely out of view when not in use, preserving sight radius and optic compatibility. When deployed, it provides a rock-solid sighting plane with clean windage and elevation functionality.

This sight is built for shooters who value simplicity and reliability. The low-profile design means it won't interfere with your primary optic setup, and the steel construction handles field use without compromise. Whether you're running a backup sight configuration or establishing iron sight fundamentals, the Defiance delivers no-fuss performance.
