The new SCAR 17S is built around a short-stroke gas piston system with a two-position adjustable gas regulator for improved reliability and suppressor optimization. A hydraulically buffered two-piece bolt carrier reduces felt recoil and promotes faster follow-up shots, contributing to smoother operation. The threaded 5/8x24 barrel profile supports compatibility with forward-venting suppressors such as the FN QD762.

Since 2008, the iconic FN SCAR has been the industry standard in gas-operated, semi-auto, modular rifles for the most demanding shooters. And now, it's even better, with more than 25 innovative upgrades for the U.S. commercial market- upgrades that are worth more than $1,000 with no price increase to consumers.
