Radian Model 1 Upper 14.5″ 6mm ARC – Brown | Ambidextrous AR Upper Receiver

The Radian Model 1 14.5″ Upper in 6mm ARC and Brown finish represents the pinnacle of precision-engineered AR platform components. Built on a simple but uncompromising design philosophy, every Model 1 upper is crafted from the highest quality raw materials using the most precise CNC machining equipment available — then hand-assembled one at a time by a trained Radian gunsmith who personally inspects, test fires, and cleans each unit before it leaves the shop.

Chamber in the hard-hitting, long-range capable 6mm ARC cartridge, this 14.5″ upper delivers exceptional ballistic performance in a compact, versatile package. Fully ambidextrous controls make it an ideal choice for both left- and right-handed shooters, removing the compromises that plague traditional AR designs. Whether you’re a competitive shooter, a serious hunter, or a demanding enthusiast, the Model 1 upper is built to perform flawlessly in the field and on the range.

The Brown Cerakote finish offers a distinctive, tactical aesthetic while providing excellent corrosion and wear resistance. And because Radian stands fully behind their craftsmanship, every Model 1 is backed by a lifetime guarantee — no exceptions, no fine print.
