FN scar 17 13inch barrel NEW
FN SCAR 17S 13″ Barrel Assembly, 7.62x51mm NATO, Factory OEM, New
So you’re SBR-ing your SCAR 17S and want the factory barrel — not a cut-down version with alignment concerns. This is the right call. The genuine FN America SCAR 17S 13″ barrel assembly, part number 98814. Cold hammer-forged, chrome-lined MIL-SPEC steel. Complete assembly including gas system and flash hider. Discontinued and no longer in production.
FN scar 17 13inch barrel NEW This is not a cut-down 16″ barrel. First, chopping a longer SCAR barrel introduces real concentricity concerns because of how OEM gas block pinning interacts with the barrel material under torch or saw heat. Next, a factory 13″ assembly eliminates that risk entirely — it’s engineered from the start for this length. Finally, it ships with everything already installed, including the front sight, gas block, gas regulator, gas piston, and flash hider. Therefore, installation is a simple user-level swap with a Torx T25 and a 62 in-lb torque wrench.
Is this FN scar 17 13inch barrel NEW legal to install on any SCAR 17S?
No, and this is critical. So a 13″ barrel on any SCAR 17S that was manufactured and sold as a rifle creates a short-barreled rifle under federal NFA law. Therefore, you may NOT install this barrel on your SCAR 17S unless it is already registered as an SBR with ATF. Also, FN America explicitly states “All NFA/ATF Rules Apply” on this product. Therefore, confirm your SCAR’s registered SBR status and ensure engraving is complete before installing this barrel.
Why buy a factory 13″ barrel instead of having a longer barrel cut down?
FN scar 17 13inch barrel NEW Precision, alignment, and reliability. So cutting down a SCAR barrel is significantly more complex than cutting an AR barrel. Also, the OEM gas block pinning on SCAR barrels can cause slight warpage when cut, creating thread concentricity problems that affect suppressor or flash hider alignment. Therefore, even top barrel professionals consider this a challenging job. The factory 13″ assembly eliminates all of that by starting at the correct length.
What’s actually included with this FN scar 17 13inch barrel NEW assembly?
A complete, ready-to-install assembly. So you get the 13″ cold hammer-forged, chrome-lined barrel with the front sight assembly, gas block assembly, gas regulator, gas piston, and flash hider all pre-installed. Also, the assembly is ready to shoot without headspacing after installation. Therefore, one swap and you’re done — no additional gas system sourcing required.
How hard is installation?
FN scar 17 13inch barrel NEW User-installable with the right tools. So FN designed SCAR barrel swaps to be done by the owner with a Torx T25 bit and a torque wrench set to 62 in-lb. Also, no headspacing is required after a factory barrel swap on the SCAR platform. However, FN recommends installation by a qualified and trained gunsmith. Therefore, if you’re not confident with the process, have a SCAR-knowledgeable gunsmith handle it.
Why is this FN scar 17 13inch barrel NEW hard to find?
It’s been discontinued. So FN America discontinued production of the 13″ SCAR 17S barrel assembly. Also, demand from the registered SBR community has absorbed most existing inventory. Therefore, new-in-bag examples are increasingly scarce, and pricing reflects that scarcity on the secondary market.

FAQ
Can I legally install this FN scar 17 13inch barrel NEW on my standard SCAR 17S? Only if it’s already registered as an SBR with ATF. Installing a 13″ barrel on a rifle-configured SCAR 17S without prior SBR registration violates federal NFA law.

Does this barrel include the gas system? Yes. The gas block, gas regulator, gas piston, and flash hider all ship pre-installed with this barrel assembly.
Does installation require headspacing? No. Factory FN barrel assemblies on the SCAR platform don’t require headspacing after installation.
