The SCAR 20S uses a gas-operated, short-stroke piston system with a rotating bolt, giving it dependable cycling with 7.62x51 NATO. It accepts SCAR-H/17-pattern magazines and ships here with one 10-round and one 20-round detachable steel magazine. Capacity is 20+1.
Its 20-inch heavy-profile barrel is made from proprietary FN steel and is chrome-lined and cold hammer-forged. The barrel is threaded and currently fitted with a SureFire ProComp 7.62 muzzle brake. This example features rifling suited for 7.62x51mm.
The precision MK20-style stock is non-folding and highly adjustable, including length of pull, comb/cheek height, and buttplate, all riding on twin guide rods. An underside accessory rail and a rubber finger-groove pistol grip round out a stable, ergonomic shooting position. The Geissele Super SCAR two-stage trigger provides a clean, repeatable pull.
A full-length, numbered MIL-STD-1913 top rail with T-marks offers extensive mounting real estate, and the handguard provides rail segments at the 3, 6, and 9 o'clock positions. Folding front and rear iron sights are installed. The monolithic aluminum upper receiver and reinforced polymer lower/trigger module wear a Flat Dark Earth finish, and factory markings indicate manufacture in Columbia, South Carolina, USA.
