The FN SCAR 17S (Special Operations Forces Combat Assault Rifle, 17S) is the civilian semi-automatic version of the military FN Mk 17 (SCAR-H "Heavy" variant). Manufactured by FN Herstal (Belgium) and imported/sold by FN America, it is a modular, gas-operated battle rifle/carbine chambered primarily in 7.62×51mm NATO (.308 Winchester).
Key Features and Design
Operating System: Short-stroke gas piston with a rotating bolt. This system runs cleaner and more reliably than direct impingement (like AR-10s), with less felt recoil and better performance when suppressed.
Modularity: Highly modular platform. Quick-change barrel system (tool-free or minimal tools), allowing swaps between different lengths/configurations. Monolithic upper receiver with extensive Picatinny rails (newer models incorporate M-LOK slots).
Stock: Side-folding and telescoping polymer stock with adjustable length of pull and cheek riser. This makes it compact for transport/storage.
Charging Handle: Early models had a reciprocating charging handle (could smack your hand). Newer NRCH (Non-Reciprocating Charging Handle) versions have ambidextrous, static handles that stay put during firing — a major improvement.
Controls: Fully ambidextrous safety, magazine release, and bolt catch.
Barrel: Cold hammer-forged, chrome-lined, free-floating with polygonal-style rifling benefits. Standard length is 16.25".
Other: Hydraulic buffer in newer generations for even softer recoil, suppressor-ready, and extremely durable construction.

Shopping at Guns.com gives you the backing of a company that is committed to your satisfaction. And unlike our competitors, it extends beyond the buying process. We get the FFL from your store – others make you find it, copy it, and fax it. We have a generous return policy, and handle everything – you don’t have to go back to the store. And our Rangemasters are here to answer all your questions about our products or process. We're bringing a level of service to the online gun buying experience that is unheard of.
Many online gun sales actually take away from your local community. Instead of buying a gun that’s on your local store’s shelf, most retailers drop ship it from a warehouse in another state. At Guns.com, if an FFL is part of our network, we sell THEIR guns first whenever possible. That way, we’re helping small businesses in your community AND if they have it in stock, you can pick your gun up IMMEDIATELY – it’s how business should be done.
Most everything can be easily bought online these days. But for some reason, buying a gun online can be complicated. Most websites are poorly organized, don’t tell you a lot about what you’re buying, and leave you on your own to figure out what you want. Guns.com is built to be simple – easily organized products, useful descriptions from experts, and support to guide you to the right choice. Spend your time enjoying the gun you want, not getting frustrated with a complex website that makes gun buying hard.
