Up to 45 business days
Every KA Tech rifle is built on internals and tuning we’ve spent the last four years perfecting. Our performance packages are the industry standard everyone else is chasing — if you want something that’s going to outperform everything else on the field, this is it.
The KA Tech MAC Retro is built around a custom Retro Arms receiver for an aggressive, old-school feel with none of the performance trade-offs. Designed with a full CNC aluminum and carbon fiber body, it delivers the same top-of-the-line KA Tech performance in a body style all its own.
This rifle is built with top-tier internals and premium external components to give players a true performance advantage — made to perform at a high level while keeping the clean, signature look KA Tech is known for.
Finished in Blackout for a stealthy, all-black look.
Choose the standard outer barrel configuration for a more traditional setup, or select the Speed Cannon configuration, which houses the tracer unit inside the carbon fiber barrel for a cleaner, more streamlined look. Both options are built to deliver fast response, excellent air efficiency, and strong consistency on the field.
Colors, CNC design, and specific requests can always be customized — just reach out.
