SAKO Unveils ARG: Next-Generation Arctic Rifle System

SAKO, the Finnish small arms manufacturer, announced 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 Defense Forces.

SAKO is launching three different models under the Sako ARG family: the Sako ARG 40 GP (Gas Piston) and DI (Direct Impingement) in 5.56×45 NATO, and the Sako ARG 50 GP, a semi-auto sniper rifle chambered in 7.62×51, included in the lineup.

The company says that, 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, which reduces heat and carbon buildup for maximum reliability; and a direct impingement system for a lighter, more streamlined design, offering refined accuracy and a smoother shooting experience.

“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.”

The ARG is fully ambidextrous, with safety selectors, magazine releases, and bolt catch mechanisms designed for intuitive operation by both left- and right-handed users. This design supports fast, instinctive handling in high-pressure scenarios.

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 requirements. Key components are interoperable with standard AR-15 systems, simplifying maintenance and logistics even in crisis situations.

Military-security cooperation between Sweden and Finland has been ongoing and intensifying for some time, as the Northern European countries collaborate to address global security challenges. Sako, a well-known and respected arms company, provides European armies with reliable weapons systems and maintains long-term relationships with regional militaries. The Swedish Army has purchased approximately 30,000 AK 24 assault rifles in 5.56 mm caliber from Sako in recent years.
