The SCAR 16S is a short-stroke gas piston semi-automatic chambered in 5.56x45 NATO, here configured with an 18 in threaded barrel and a multi-port flash-suppressing compensator. It retains the monolithic aluminum upper receiver with a polymer lower and wears the factory Flat Dark Earth finish. The upper is Belgian-marked, with FNH USA Columbia SC import information, and the model is marked "SCAR 16S cal. 5.56x45."
Controls and ergonomics are enhanced with a PMM extended bolt-release lever and a Magpul AR-pattern pistol grip in FDE. The factory polymer stock side-folds, telescopes, and offers adjustable length of pull with a rubber buttpad. A right-side charging handle and two-position gas regulator support reliable operation and user tuning.
Modularity is a strong point on this example. The installed Parker Mountain Machine M-LOK handguard expands accessory mounting options, while the full-length, T-marked MIL-STD-1913 top rail provides continuous mounting space along the receiver. Factory folding sights include a gas-block-mounted front and a diopter drum rear.
The Geissele Super SCAR two-stage trigger is installed, offering a refined fire-control setup within the factory layout. Capacity is 30+1 with AR-pattern magazines, and this rifle ships with two 30-round mags, including a Magpul PMAG and a Lancer L5AWM (the L5AWM is shown sealed).
