Product Description

The Rock River Arms CAR A4 Complete Upper Receiver is chambered in .350 Legend and built for shooters who demand reliability, precision, and versatility from their AR-15 platform. This complete upper features a 16-inch chrome moly steel barrel with a 1:16 twist rate, threaded at 1/2-36 TPI and fitted with the RRA Operator Muzzle Brake to reduce felt recoil and improve follow-up shot accuracy. The forged aluminum A4 flat-top upper receiver pairs with an RRA 13-inch Extended Lightweight Free Float M-LOK Handguard, offering a full-length Picatinny top rail and M-LOK accessory slots along the handguard for bipods, foregrips, lights, and more. A low-profile gas block and carbine-length gas system round out the reliable operating package. Delivered ready to mount on any mil-spec AR-15 lower receiver, this upper includes a bolt carrier group, charging handle assembly, and one 10-round magazine, making it an outstanding option for completing a build or swapping calibers with ease.
