The FN SCAR 16 and SCAR 17, designed by FN Herstal for military use and adapted for the civilian market, are among the most recognizable modern battle rifles available today. These rifles offer exceptional modularity, rugged durability, and proven performance in some of the harshest conditions worldwide. Featuring folding stocks, free-floated barrels, and high-end build quality, the SCAR series remains a top-tier option for tactical shooters, enthusiasts, and professional operators.

Introduction: Battle-Proven Design for Modern Shooters
The FN SCAR (Special Operations Forces Combat Assault Rifle) platform was developed in the early 2000s to meet the requirements of U.S. Special Operations Command (SOCOM). Its goals were to deliver a lightweight, modular, and highly reliable combat rifle capable of adapting to multiple mission profiles. The SCAR 16 and SCAR 17 — civilian semi-automatic variants of the SCAR-L (light) and SCAR-H (heavy) — bring that same level of innovation and performance to professional shooters, competitors, and enthusiasts.

Standout Features
Short-Stroke Gas Piston System
The SCAR platform uses a short-stroke gas piston system that runs cleaner and cooler than traditional direct impingement, enhancing reliability and reducing maintenance in harsh environments.
Folding, Telescoping Stock
The adjustable folding stock allows for compact transport and storage, while providing multiple length-of-pull settings and an adjustable cheek riser for optimal shooter comfort.
Monolithic Upper Receiver
The SCAR’s monolithic aluminum upper receiver offers superior rigidity and a full-length Picatinny top rail, making it easy to mount optics, night-vision devices, and other accessories without compromising zero.
Free-Floated, Chrome-Lined Barrel
The cold hammer-forged, chrome-lined barrel provides excellent longevity and consistent accuracy. The barrel is also user-changeable (with the proper tools), allowing shooters to adapt to different calibers or mission profiles.
Enhanced Ergonomics
Ambidextrous controls, a non-reciprocating charging handle (on newer models), and low-recoil impulse make the SCAR series comfortable and intuitive for a wide range of shooters.
Performance in the Field
Accuracy
The SCAR 16 typically delivers 1–1.5 MOA accuracy with quality ammunition, while the SCAR 17 offers similar or slightly better precision in .308 Win. This level of performance is excellent for service-grade rifles designed for reliability and field use.
Recoil & Handling
Both rifles are known for their manageable recoil thanks to the piston-driven system and effective muzzle devices. The SCAR 17’s .308 Win chambering has slightly more kick but remains highly controllable compared to other .308 rifles.
Reliability
Field-tested in combat environments worldwide, the SCAR platform is exceptionally reliable in adverse conditions such as sand, mud, and extreme temperatures.

Maintenance & Care
The SCAR platform is known for low-maintenance requirements thanks to its piston system. Routine cleaning of the bolt carrier, piston assembly, and barrel after extended range sessions or field use helps maintain peak performance. Proper lubrication of the bolt and rails ensures smooth cycling and reduces wear over the long term.
