Design and Performance

The bullpup architecture shortens the overall length while preserving barrel length, enhancing maneuverability in close-quarters and confined environments. The dual-tube feeding system increases mission flexibility by allowing instant selection between different ammunition types such as buckshot and slugs. The combination of a 4140 steel bolt and barrel assembly with a polymer outer housing provides a balanced structure of durability and weight. The full-length top rail and broad gripping surfaces facilitate the integration of optics and flashlights while supporting controlled pump operation. Due to the bullpup configuration, a link-trigger mechanism is employed; proper assembly technique and regular maintenance significantly enhance system reliability.

Production and Testing Process

The platform is manufactured in Türkiye by UTAŞ. Metal components are machined from thermally treated 4140 steel while housing parts are formed from fiber-reinforced polymer. Assembly groups are designed for easy field disassembly and include modular components that can be separated without tools or with minimal tools for basic maintenance. During series production, functionality, feeding reliability, firing consistency and coating durability are regularly inspected; additional tests such as drop resistance and environmental endurance may be conducted depending on market requirements or tender specifications.
