The rifle is built around a 7075-T6 forged aluminum Aero Precision X15 lower receiver marked "AERO PRECISION INC., TACOMA, WA," "MODEL X15," and "CAL MULTI." The upper is a mil-spec pattern flat-top with a T-marked Picatinny rail (T2–T12), providing a solid receiver interface and rail reference points.
The 16-inch barrel uses a 1:9 twist and is threaded, fitted with an A2 birdcage flash hider. A direct-impingement gas system drives the action, and the rifle feeds from a detachable STANAG-pattern magazine in 5.56mm NATO.
Magpul furniture in FDE includes a MOE carbine-length two-piece polymer handguard, STR adjustable carbine stock, and a polymer pistol grip. An enhanced polymer trigger guard and angled foregrip round out the controls. Length of pull is listed at 13.5 inches.
Sighting equipment consists of an A2 front sight base paired with a flip-up polymer rear sight on the receiver rail. A cylindrical weapon light is mounted forward of the handguard in a tan ring clamp. The buffer tube is marked "Made in USA," and the rifle is finished in Type III hardcoat anodizing.
