FN SCAR® 17S Rifle – 7.62 NATO / 6.5 Creedmoor Modular Carbine
The FN SCAR® 17S is the benchmark for gas-operated, semi-automatic battle rifles, engineered for shooters who demand durability, adaptability, and consistent performance. Originally introduced in 2008, the SCAR platform has evolved into a refined system featuring 25+ upgrades for the commercial market—without increasing MSRP.
This latest-generation SCAR 17S heavy carbine delivers reduced felt recoil and faster follow-up shots through a hydraulically buffered, two-piece bolt carrier, paired with an extended receiver and M-LOK forearm for enhanced ergonomics and modularity. Built around FN’s proven short-stroke gas piston system, it maintains reliability across a wide range of conditions, including suppressed use.
