The FN SCAR 17S is a semi-auto .308/7.62 NATO rifle from FN America / FN Herstal (brand part no. 38-102017-100), built as the modular, gas-operated heavy carbine that has set the standard for military-grade rifles since 2008. This next-generation SCAR 17S brings more than 25 upgrades to the commercial market, including a hydraulically buffered, two-piece bolt carrier that reduces felt recoil and speeds up follow-up shots. Suppressor-compatible and tested to 16,000 rounds, it pairs a 16.25-inch barrel with a 20-round capacity and an extended receiver and forearm for added modularity. Whether it’s built out for competition, defensive use or serious range work, the SCAR 17S retains the look and performance that made the platform legendary.
