The FN 15 Carbine combines FN’s AR-15 platform with a 16-inch threaded barrel capped by an A2-style birdcage flash hider. Its carbine-length, direct-impingement gas system runs under a fixed, F-marked A2 front sight base that also includes a bayonet lug and front sling attachment point.
The flat-top upper provides a T-marked Picatinny receiver rail along with a shell deflector, forward assist, and ejection-port cover. A folding rear backup iron sight is installed on the rail, complementing the fixed A2 front sight for a complete iron sight setup out of the box.
Furniture includes two-piece, ribbed polymer carbine-length handguards with heat shields, an A2-style pistol grip, and an FN-branded 6-position collapsible stock in matte black. The stock features a sling loop and an FN medallion on the buttplate, with a listed length of pull of 10.0 inches.
The matte black aluminum receiver set is cleanly marked, with the lower receiver stamped 'MODEL FN15' and 'CALIBER MULTI'. Capacity is 30+1, and this rifle ships with two 30-round Magpul PMAG GEN M2 windowed magazines. A delta ring is present for the handguards, and sling points are provided under the front sight base and at the stock toe.
