Description
The FN SCAR 20S 6.5 Creedmoor, 20″ Chrome Lined Barrel, Black, 20rd is a purpose-built, semi-automatic precision rifle designed for long-range accuracy. It’s the factory-refined evolution of the battle-proven SCAR platform, chambered in the inherently flat-shooting 6.5 Creedmoor cartridge. I’ve put several hundred rounds of match-grade ammo through this system, and it’s built to deliver consistent, sub-MOA performance straight from the case. At $4087.96, it’s a serious investment for a serious shooter who demands a rifle that fits out of the box and performs without modification.
Key Features
- 20″ Chrome-Lined Cold Hammer-Forged Barrel: Provides exceptional durability, extended barrel life, and consistent accuracy. The chrome lining is a huge plus for maintenance and longevity, especially if you’re running high round counts.
- 6.5 Creedmoor Chambering: Offers superior ballistic performance over 7.62 NATO at distance, with less wind drift and more retained energy.
- Fully-Adjustable Geissele Super SCAR Trigger: A fantastic two-stage trigger right from FN—crisp, predictable, and a massive upgrade over a standard mil-spec pull.
- Non-Reciprocating Charging Handle & Improved Bolt Catch: Enhances ergonomics and allows for easier manipulation without interfering with optics or your support hand.
- Folding & Adjustable Stock: Features a fully-adjustable cheek riser and length of pull, letting you get a perfect weld for any optic height. It folds for compact storage or transport, too.
Specifications & Details

| Barrel Length | 20 Inches |

That 12-pound weight is a feature, not a bug. It adds stability from prone or a bench, soaking up recoil and making the 6.5 Creedmoor feel even milder. The gas piston system runs incredibly clean and cool compared to a direct-impingement AR-10, which is a real benefit during long strings of fire. The rifle comes with a single 20-round magazine, and it’s compatible with FN SCAR 17S/20S pattern mags, giving you plenty of aftermarket and OEM options. Here’s the thing—this isn’t a tweaked battle rifle; it’s a ground-up precision tool. The receiver has an integrated, continuous Picatinny rail for optics, and the barrel is free-floated within the handguard to maximize accuracy potential.
Who This Rifle Is For
This is for the precision rifle competitor who wants a semi-auto edge in PRS or similar matches, or the serious long-range enthusiast who values rugged reliability and repeatable performance above all. It’s also an ideal duty rifle for certain professional applications where a designated marksman needs a tool that bridges the gap between a standard-issue rifle and a full-size bolt gun. If your primary goal is plinking or lightweight hunting, there are better, cheaper options. This rifle has a specific job.
Pros & Cons
Pros: Unmatched out-of-the-box accuracy for a semi-auto platform. The legendary SCAR reliability and durability in a precision format. The superb, adjustable stock and fantastic trigger eliminate the need for immediate upgrades. The chrome-lined barrel means you can shoot it hard without worrying about throat erosion too quickly.
Cons: The price tag is significant. It’s heavy, so it’s not a rifle you’ll want to carry for miles on a hunt. While the aftermarket is growing, it’s not as vast as the AR-10 world. Some proprietary parts mean you’re largely tied to FN for critical spares.
Frequently Asked Questions
Q: Is the SCAR 20S just a SCAR 17 rebarreled for 6.5 Creedmoor?
A: No, it’s a distinct model. While they share the core operating system, the 20S has a heavier, fully free-floated barrel, an improved non-reciprocating charging handle, an enhanced bolt catch, and a different receiver geometry for the extended rail. It’s a dedicated precision variant.
Q: What optics mount height works best with the adjustable cheek riser?
A: I’ve found that a standard 1.5-inch height (like a lower-third co-witness mount) or a 1.93-inch mount pairs perfectly with the stock’s adjustment range when using a large 34mm or 35mm scope tube. This allows for a natural, heads-up shooting position.
Q: Can I convert a SCAR 17S to 6.5 Creedmoor?
A: Technically, with a barrel and bolt head change, yes. But you won’t get the free-floated handguard, the improved controls, or the same guaranteed accuracy. The 20S is a complete, optimized system. For true precision work, starting with the dedicated platform is the right call.
Look, if you need a semi-automatic rifle that can reliably hit targets at 800+ yards and handle the rigors of competition or demanding use, the FN SCAR 20S is one of the best factory options available. It’s a professional-grade instrument that ships to Missouri and compliant US states. If this level of performance aligns with your needs, see the current availability and pricing on our site.
