The FN SCAR 17S .308 Winchester stands as a testament to combat-proven engineering, delivering formidable .308 Winchester (7.62x51mm NATO) power in an exceptionally reliable and adaptable platform. Designed and built to FN’s rigorous standards, this rifle ensures operational effectiveness and consistent performance across diverse conditions and operational requirements.
Key Features
Robust Construction
The FN SCAR 17S features a monolithic upper receiver, precision-machined from a single block of aluminum. This design ensures superior rigidity, providing a stable and consistent platform for optics and accessories. The lower receiver is constructed from durable, impact-resistant polymer, contributing to overall weight reduction without compromising structural integrity. The rifle is finished in a non-reflective black, enhancing its utility in tactical applications.
Gas Piston System
Utilizing a short-stroke gas piston system, the SCAR 17S delivers exceptional reliability and a reduced recoil impulse. This self-regulating system effectively mitigates carbon fouling in the receiver, significantly enhancing sustained operational capability and reducing maintenance requirements. The system is designed for consistent cycling across a broad spectrum of ammunition types and varying environmental conditions.
Ergonomics and Adaptability
The SCAR 17S integrates a folding, telescoping polymer stock that offers adjustable length of pull and cheek height. This allows operators to achieve a personalized fit, optimizing comfort and sight picture. Ambidextrous controls, including the safety selector and magazine release, facilitate seamless operation for both left and right-handed users. The non-reciprocating charging handle can be configured for either side, further enhancing user adaptability and safety. A full-length Picatinny top rail and additional accessory rails at the 3, 6, and 9 o’clock positions provide extensive mounting options for optics, lights, lasers, and other mission-critical equipment.
Precision and Performance
Equipped with a 16-inch cold hammer-forged, chrome-lined, free-floating barrel, the SCAR 17S ensures sustained accuracy and extended service life. The 1:12 right-hand twist rate is optimized for stabilizing standard 7.62x51mm NATO and .308 Winchester projectiles. Integrated, adjustable flip-up front and rear iron sights offer immediate utility and serve as a reliable backup system for primary optics. The .308 Winchester chambering provides significant terminal performance, flat trajectory, and extended effective range, making it suitable for a wide array of demanding engagements.
