The first bosnian rifle Alfa AC-SMG9

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


Blow Back System

The simple and reliable blow back 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.

Upper Receiver

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 handguards are provided in aluminum or highly resistance polymer and can be changed easily with a quick attachment mechanism. Following latest trends and reports a M-look system has been used to allow for individual mounting of any kind of 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.

Lower Receiver

The lower receiver is made of lightweight aluminum or high-resistance polymer, reducing the total weight of the gun and absorbing the recoil of the system. 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.

Fire Selector

In order to provide maximum comfort and safety an ambidextrous fire selector has been designed with easily recognizable icons allowing to see and feel the modes even in low-light conditions.


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 3 different rubber back-plates, allowing easier handling in different positions and for different operation purposes.


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