The FN SCAR 17S .308 WIN rifle represents a battle-proven platform engineered for demanding operational parameters. Chambered in .308 Winchester, this rifle integrates a 16-inch cold hammer-forged barrel, crucial for achieving consistent ballistic performance and extended service life. The Flat Dark Earth (FDE) finish provides enhanced corrosion resistance and signature management in varied environmental contexts.
This system’s operational integrity is derived from its self-regulating, short-stroke gas-piston operating system. This design choice effectively mitigates felt recoil and ensures reliable cycling across diverse ammunition types and environmental conditions, thereby optimizing user control and operational tempo. The robust construction is anchored by a monolithic aluminum receiver, which provides a stable interface for barrel and optics mounting, minimizing potential points of flex or stress that could compromise repeatable zero.
Key Features
Operating System
The short-stroke gas-piston operating system provides consistent, reliable cycling and significantly reduces carbon fouling in the receiver group, decreasing maintenance intervals and enhancing long-term operational reliability. This system’s design also contributes to reduced recoil impulse, facilitating faster follow-up shot acquisition.
Receiver Construction
A monolithic aluminum upper receiver serves as the foundation, ensuring structural rigidity and a consistent mounting surface for optics and accessories via an integrated MIL-STD-1913 Picatinny rail. This design choice eliminates component flex, preserving the weapon system’s precision characteristics under dynamic conditions.
Barrel Construction
The 16-inch cold hammer-forged, free-floating barrel is manufactured for superior inherent accuracy and prolonged barrel life. Its specific contour and rifling twist rate are engineered to stabilize a broad spectrum of .308 Winchester projectile weights, optimizing ballistic coefficients for various engagement distances.
Ergonomics and Adaptability
The SCAR 17S features an adjustable, folding stock and ambidextrous controls, allowing for rapid adaptation to operator preference and tactical requirements. An extensive MIL-STD-1913 rail system provides ample real estate for the integration of mission-essential accessories, including optical sights, illumination devices, and laser designators.
Finish
The application of a Flat Dark Earth (FDE) finish provides a durable, non-reflective coating that enhances the rifle’s environmental resilience against abrasion and corrosion while also contributing to visual signature disruption in open terrain.
