The STEYR 9MM CONVERSION KIT FOR AUG from Steyr is designed to let AUG enthusiasts train and practice with 9mm ammunition while preserving the same feel and manual of arms as their 5.56x45mm duty setups, making it an ideal choice for training, plinking, or defense. This kit features a 16" 9x19mm barrel with a 1:10 twist that is threaded 1/2x28, a complete trigger pack, a 9x19mm bolt carrier group, and a 28-round waffle style magazine, all tailored to fit the STEYR AUG (not compatible with NATO models) and delivered in a matte black finish. With its rugged construction and true-to-duty operation, the kit enables realistic handling, sighting, and cycling in a compact, single-paragraph experience that highlights how each component contributes to reliable performance, ease of maintenance, and broad training applications. The 28-round capacity provides ample range time, while the threaded barrel allows versatile use with common suppressors or accessories, giving shooters a practical, hands-on approach to 9mm training that mirrors their standard AUG procedures.
