The CZ BREN 3 is a modular, multi-caliber assault rifle available in 5.56×45mm NATO and .300 AAC Blackout calibers. It features a short-stroke gas piston system with a three-position adjustable gas block, enhancing its performance with suppressors and under adverse conditions. The rifle's construction includes a 7075-T6 aluminum alloy upper receiver and a polymer lower receiver, contributing to a lightweight design. Barrel lengths range from 7 to 16.5 inches, allowing for customization based on mission requirements. Additional features include an ambidextrous, non-reciprocating charging handle, M-LOK handguard, and a folding, telescopic stock.

The development of the CZ BREN 3 was influenced by feedback from various military users, including the Czech Army and Ukrainian forces, who have utilized previous BREN models in combat situations. This input led to enhancements in durability, ergonomics, and modularity, ensuring the rifle meets the evolving demands of modern warfare. The CZ BREN series has a history of adoption by multiple international forces, such as France's GIGN, the Mexican Federal Police, and the Hungarian Armed Forces.

Compared to its predecessor, the CZ BREN 2, the BREN 3 offers improved modularity with quick-detach attachment points and an updated stock interface for increased durability. Its design facilitates rapid caliber and barrel changes, providing operational flexibility. When compared to other modern rifles like the FN SCAR or HK416, the BREN 3 stands out for its balance of performance, adaptability, and cost-effectiveness.

Strategically, the CZ BREN 3 enhances the Czech Republic's position in the global defense market by offering a domestically produced, NATO-compatible assault rifle. Its modular design aligns with the trend towards adaptable weapon systems capable of meeting diverse mission profiles. The rifle's adoption by various international forces underscores its reliability and effectiveness in different operational contexts.

While specific budgetary details and recent contracts for the CZ BREN 3 have not been disclosed, its introduction at IDET 2025 indicates CZ's intent to market the rifle to both domestic and international clients.
