The Alfa AC-SMG9 Submachine Gun has been designed to fit law enforcement requirements, allowing easy handling through the compact conception. The small size and weight result in smooth handling in vehicles and buildings while also granting long-range capabilities by using the extractable stock.


The Alfa AC-SMG9 has been specially developed for the special forces of Bosnia, requesting a reliable product for professional users. The overall design provides a one-fits-all solution for various users and purposes within different forces. The result is a multi-purpose weapon for modern urban requirements.

The Alfa AC-SMG9 is fully compatible with weapons of the M16 and M4 family, providing a simple and reliable blowback system in the caliber of 9×19, allowing for easy cleaning and maintenance and reliable functioning. The Alfa AC-SMG9 is produced with the highest technical standards, considering the real needs of modern police and military forces. Together with the used materials and surfaces, the technology guarantees simple maintenance, functionality, and performance in all environments and conditions.

The company behind this submachine gun is AC Unity. It is a company fully licensed to manufacture and trade military weapons and ammunitions of all types and is based in the industrial zone of Goražde (Bosnia and Herzegovina), surrounded by many other companies in this sector, allowing to use all possible synergies with the metal industries and manufacturers of related products.


The simple and reliable blowback system not only makes the cleaning and maintenance easier for the users in the field but also reduces the felt recoil, especially when fired in the full-automatic mode.

The upper receiver is made from 7075 aluminum alloy with a hard anodized surface, making it highly resistant and durable. Barrel length is available in two dimensions, 7,5″ and 10,5″.

The retractable polymer buttstock provides various points to attach quick-detachable swivel slings and can be extended to 5 different lengths positions. In addition, each buttstock comes with three rubber back-plates, allowing easier handling in different positions and for other operational purposes.

To provide maximum comfort and safety, an ambidextrous fire selector has been designed with easily recognizable icons allowing you to see and feel the modes even in low-light conditions. The lower receiver is made of lightweight aluminum or high-resistance polymer, reducing the gun’s total weight and absorbing the system’s recoil. The magazine well accepts 9mm magazines of different capacities and provides finger groves in the front.

Any standard AR-15 grip can be chosen and mounted by the user. The handguards are provided in aluminum or high resistance polymer and can be changed easily with a quick attachment mechanism. Following the latest trends and reports, an M-look system has been used to allow for individual mounting of any additional rails in different positions and, at the same time, provide a more comfortable handling and lower total weight, even in the metal version of the handguard.
