The rifle uses a semi-automatic, direct-impingement operating system on the AR-15 platform. The flat-top upper receiver includes a forward assist and case deflector, and the selector is clearly marked “SAFE” and “FIRE.” No iron sights are included, leaving the full-length top Picatinny rail open for mounting as needed.
The free-float M-LOK aluminum handguard (approximately 15 inches) provides ample attachment real estate and maintains a continuous, T-marked top rail from receiver to muzzle end. The 16-inch barrel is threaded and fitted with a three-prong flash hider.
Furniture includes an adjustable, telescoping polymer carbine stock with an integral QD sling cup, paired with an A2-style polymer pistol grip with a finger groove. The lower receiver is rollmarked “MODEL FN15 / CALIBER MULTI.”
The rifle feeds from detachable box magazines and is configured for a 30+1 capacity with the included 30-round magazine. A standard AR-15 7-lug bolt is visible, and the manual safety provides straightforward, familiar controls.
