KA Tech MAC Polarstar AR7 V MSG/ESG HPA M4 Cherry Blossom

Built to dominate on the field, the KA Tech MAC AR7 V is a premium custom HPA rifle engineered for players who want the highest level of accuracy, speed, durability, and customization. Designed with a full CNC aluminum and carbon fiber body, this platform delivers the perfect balance of lightweight handling, aggressive styling, and competition-ready performance.

This rifle is built with top-tier internals and premium external components to give players a true performance advantage. Whether you are snapping between targets in close quarters or demanding maximum consistency shot after shot, the MAC AR7 V is made to perform at a high level while maintaining the clean, signature look KA Tech is known for.

The AR7 V can be configured in two distinct setups to match your playstyle. Choose the standard outer barrel configuration with a 200mm inner barrel for a more traditional setup, or select the Speed Cannon configuration with a 155mm inner barrel, which houses the tracer unit inside the carbon fiber barrel for a cleaner and more streamlined look. Both options are built to deliver fast response, excellent air efficiency, and strong consistency on the field.

Every build is assembled around premium parts, proven HPA performance, and the flexibility serious players demand. From competitive speedsoft builds to highly customized personal setups, the KA Tech MAC AR7 V is built to give you an edge in performance, function, and style.
