In the world of modern sporting rifles, precision and reliability are paramount. The Rock River Arms A4 Carbine Upper delivers both in spades. Chambered in the potent .350 Legend, this upper assembly is designed for those who demand excellence from their firearm components.
The heart of this system is a 16-inch chrome moly barrel with a 1/16 twist rate, engineered to provide optimal stability and accuracy for each shot fired. This choice of material ensures durability while maintaining lightweight characteristics essential for maneuverability.
Complementing the robust barrel is a Rock River Arms 13-inch M-Lok compatible free float rail. This feature not only reduces weight but also offers superior versatility when it comes to mounting accessories such as optics or tactical lights—an indispensable advantage for any serious shooter.
The inclusion of the RRA Operator Brake with its precise 1/2-36 thread further refines control by mitigating recoil and muzzle rise, allowing you to stay on target through rapid fire sequences.
This complete package includes everything necessary right out of the box: a bolt carrier group known for smooth operation, an efficient charging handle assembly that enhances ease-of-use under stress conditions, and even a reliable 10-round magazine tailored specifically for your ammunition needs.
For those seeking an upgrade that combines innovation with tradition without compromising performance or integrity—the Rock River Arms A4 Carbine Upper stands ready to meet your demands on any range or field expedition.
