The FN SCAR 17S .308 Winchester 13-Inch Replacement Barrel (brand part number 98814) is a genuine factory FN barrel built for the SCAR 17S platform, chambered in .308 Winchester/7.62 NATO. This barrel gives SCAR owners and armorers a direct factory-spec replacement for a worn barrel or a way to configure a shorter-barrel SCAR upper, backed by the same manufacturing standards FN applies to its military and law enforcement contracts. It ships as a complete barrel assembly with the gas system and front sight already installed, and no receiver.

Frequently Asked Questions

Does this barrel come with a front sight? Yes, this complete barrel assembly ships with the gas block, gas regulator, gas piston, flash hider, and flip-up front sight already installed.

Is a 13-inch barrel legal to own on its own? Yes, a bare 13-inch barrel is an ordinary Title I part. Federal law restricts how it can legally be installed — under 16 inches on a rifle-configured, shouldered SCAR lower without proper registration would create an unregistered short-barreled rifle, so it should be paired only with a pistol-configured build or a properly registered SBR receiver.

Will this fit any SCAR receiver? This barrel is built to genuine FN SCAR 17S specifications for a direct factory fit on that platform.
