The A4 upper receiver provides a T-marked Picatinny top rail (T2–T12) along with a forward assist, ejection-port cover, and integral case deflector. The fixed A2 front sight base pairs with the carbine-length gas system for a classic M4-style configuration.
The 16" chrome-moly steel barrel uses an M4 profile and is threaded 1/2x28 to accept compatible muzzle devices. Its 1:9 twist supports common 5.56mm NATO loads, and the bore shows strong, sharp rifling.
Furniture is Rock River Arms-branded, including a 6-position collapsible stock and an overmolded A2-style pistol grip with finger grooves. Length of pull is approximately 10.5–14 inches. The carbine-length, two-piece ribbed polymer handguard completes the M4-style setup.
Sling attachment points include a front sling swivel on the FSB and an integral loop at the stock toe. Controls include a manual safety and a standard charging handle. Capacity is 30+1 with the included magazine.
