The Heresy Design 9mm AUG conversion kit transforms your Steyr AUG platform into a dedicated 9mm shooter. This 16.1-inch barrel and carrier group setup ships complete and ready to install in your AUG A3M1 with either NATO or standard stock—no gunsmithing required. If you run a suppressed 9mm build or want to add a softer-shooting, cheaper-to-feed caliber to your AUG arsenal, this quick-change system delivers the flexibility without the headaches.
The direct blowback operating system pairs with Heresy's 3-lug suppressor mount (1/2x28 threaded) to keep gas signature manageable when running cans. The barrel assembly uses Isonite-coated wear parts—the same durable internals you'd find in precision ARs—paired with anodized aluminum quad rails for mounting options. You get AR15-pattern wear parts compatibility, which means springs, firing pins, and extractors are sourced from the largest aftermarket ecosystem in existence.
Installation is straightforward: field-strip your upper, swap the barrel and carrier, and you're ready to run. The kit includes the barrel, carrier group, and a dedicated magazine. This is purpose-built for AUG shooters who want to shoot 9mm suppressed without the fighting the gas blowback you'd get from a rifle-length system. Whether you're workshopping a specialized training load-out or just adding another affordable cartridge to your rotation, this conversion kit handles the job with proven Heresy Design engineering.

Frequently Asked Questions
Will this conversion kit fit my Steyr AUG?
Yes—this kit is designed for the Steyr AUG A3M1 and works with both NATO and standard stock configurations. It is not compatible with Steyr AUGA3 SA models, so verify your platform before ordering.
Can I shoot this suppressed?
Absolutely. The 3-lug suppressor mount with 1/2x28 thread is factory-integrated, and the direct blowback system produces minimal gas blowback—one of the main advantages of a 9mm conversion in this caliber and barrel length.
What's included in the kit?
The kit ships with a complete barrel assembly, a carrier group, and a magazine matched to the 9mm platform. Everything you need for installation is included; no additional parts required for a basic functioning setup.
Do I need to send my upper to a gunsmith?
No. This is a drop-in conversion designed for field-strip installation. Remove your existing barrel and carrier, swap in the Heresy components, and you're done. No permanent modifications to your AUG receiver are necessary.
