No, the K-Zero Plate Carrier does not include quick-release buckles. It features a standard Velcro closure system for secure and reliable use. However, you can purchase First Spear Tubes Quick Release Buckles or ROC Quick Release buckles separately and attach them by replacing the default Velcro panels on the K-Zero Plate Carrier.
