Radian Weapons 6mm ARC 14.5" Complete Upper Receiver FDE

A 14.5 inch 6mm ARC upper is a compelling piece of math. The cartridge was built for efficiency, so even from a shorter barrel it holds velocity and energy that 5.56 cannot touch, keeping ethical hunting power and long steel capability in a package sized like a fighting carbine. Radian Weapons builds this complete upper with the machine work that made the company's reputation, tight receiver fit and finish quality that shows the moment you pick it up.

The Flat Dark Earth finish pairs cleanly with the most common accessory colorways. Confirm barrel and muzzle configuration plans for your lower before building, then enjoy an AR that hits harder than its size suggests.
