Riihimäki, Finland – August 25, 2025 – SAKO proudly announces the launch of the Sako ARG – Arctic Rifle Generation, a next-generation full-auto rifle system developed in close collaboration with the Finnish and Swedish DefenceForces. Designed to replace legacy assault rifles, the ARG platform is purpose-built for Arctic warfare and tested to NATO D14 standards, delivering unmatched reliability, modularity, and mission adaptability for military and law enforcement professionals.
The Sako ARG is based on the proven AR-15 platform, enhanced with advanced engineering to meet the demands of modern combat. It features two distinct operating systems: a short-stroke gas piston system for extreme environments, reducing heat and carbon buildup for maximum reliability—and a direct impingement system for a lighter, more streamlined design with refined accuracy and a smoother shooting experience.
SAKO launches three different models under the Sako ARG family. Sako ARG 40 GP (Gas piston) and DI (Direct impingement) in 5.56×45 Nato. Also, Sako ARG 50 GP, a semi-auto sniper rifle chambered in 7.62×51, is included in the line-up.
“The SAKO ARG is more than a rifle, it’s a mission-ready system designed to protect what matters most,” said Juuso Austin, Vice President – Defence & Law Enforcement Business Unit at SAKO “It’s built for those who operate where others hesitate.”
Purpose-built for the modern war fighter
The ARG is fully ambidextrous, with safety selectors, magazine releases, and bolt catch mechanisms, ensuring intuitive operation for both left- and right-handed users. This design supports fast, instinctive handling in high-pressure scenarios.
Each rifle is equipped with a SAKO match-grade trigger unit, delivering a clean, consistent break for enhanced accuracy and control. The cold-hammer forged barrel, crafted from high-grade materials and hard-chrome lined, provides long-term durability and maintaining accuracy over thousands of rounds.
The ARG’s modular architecture includes a configurable rear stock and forend, with standardized mounting systems such as Picatinny, M-LOK, and AR-compatible components. Operators can easily attach optics, thermals, lasers, and other tactical accessories, tailoring the rifle to mission-specific profiles. Key components are interoperable with standard AR-15 systems, simplifying maintenance and logistics, even in crisis scenarios.
“We designed the ARG to give clients the freedom to choose the right configuration for their needs,” said Sami Vaajamo, Senior Product Group Manager at SAKO. “Whether you’re in a frozen tundra or a dense urban environment, the ARG adapts without compromise.”
Tested. Trusted. Tactical.
The ARG rifles have undergone rigorous testing in the arctic as well as muddy and sandy conditions, ensuring operational readiness in the harshest environments. Designed as a complete system replacement, the ARG integrates seamlessly with client’s weapon systems and supports full lifecycle management, including training, maintenance, and future modernization.
“The development of the SAKO ARG platform began over a decade ago with a clear mission: to create a modern, modular rifle system capable of replacing legacy assault rifles across military and law enforcement forces,” said Miikka Tamminen, Vice President – Research & Development at SAKO. “From day one, we prioritized real-world performance. That meant working hand-in-hand with professional users from defense organizations, incorporating their feedback into every design iteration—from ergonomics and modularity to reliability and maintainability.”
“The ARG has been tested far beyond standard requirements. In addition to rigorous NATO D14 environmental and durability testing, we push our rifles to failure in-house to understand their true limits. These insights are not just data—they’re design tools that help us build a stronger, more resilient system.”
Beyond the rifle, SAKO offers a full ecosystem of compatible accessories, including optics, thermal and night vision systems, laser designators, and tactical cases, delivered through a trusted global partner network.
Each ARG system is supported by a full lifecycle management program, including operator and armorer training, spare parts provisioning, and modernization services, ensuring seamless integration and long-term operational readiness.
