Description
This is the real deal from FN America: a complete 14-inch barrel assembly built to the same standard as the barrels found on the SCAR 16 platform. It's cold hammer-forged from chrome-lined MIL-SPEC steel and chambered in 5.56x45mm NATO, so you're getting a factory part rather than an aftermarket knockoff. The shorter 14-inch length trims weight and quickens the balance up front, which pays off when you're working in tighter spaces or just want a rifle that points a little faster.
What Comes With the SCAR 16S Barrel Assembly
One of the best things about this setup is that it arrives ready to run. The barrel ships with the flip-up front sight, gas block, gas regulator, gas piston, flash hider, and Picatinny rail section already installed. There's no piecing together a parts list or hunting down small components. It runs a 1:7 right-hand twist, which handles the full range of common 5.56 and .223 bullet weights without complaint.
Swapping the FN SCAR 16 Barrel at Home
FN designed the SCAR barrel system to be genuinely user-serviceable, and this assembly proves it. All you need is a Torx T25 and a torque wrench set to 62 in-lbs to make the swap, and there's no headspacing to fuss with once it's buttoned up. That means you can change lengths or freshen up a worn barrel on your own bench instead of shipping the rifle off to a smith.
Cold hammer forging is the reason these barrels have such a strong reputation. The process tightens up the grain structure of the steel for better longevity, while the chrome lining fights corrosion and holds up well under sustained shooting. Whether you're building out a shorter SCAR configuration or replacing a barrel that's seen plenty of rounds, this is the part that keeps a proven rifle running like it should.

Frequently Asked Questions
Will this barrel assembly fit any SCAR rifle?
This assembly is made specifically for FN SCAR 16 rifles chambered in 5.56x45mm NATO. It will not fit the SCAR 17 or other calibers, so make sure your rifle is the 16-series 5.56 platform before ordering.
Do I need a gunsmith to install the SCAR 16S barrel assembly?
No, FN built this system to be swapped at home. You only need a Torx T25 and a torque wrench set to 62 in-lbs, and there's no headspacing to deal with since the barrel is ready to shoot once it's torqued down.
What twist rate does this 14-inch barrel have?
It runs a 1:7 right-hand twist, which is the standard for the SCAR platform. That twist stabilizes heavier match and defensive loads while still shooting lighter 5.56 and .223 bullet weights well.
Is this a genuine FN factory part?
Yes, this is a factory FN America barrel assembly, part number 98804. It's built to the same cold hammer-forged, chrome-lined MIL-SPEC standard as the barrels that come on the rifle from the factory.
