The Radian Weapons Model 1 Complete Upper (brand part number R0471) is a fully assembled AR-15 upper chambered in .223 Wylde, built around a 16-inch barrel and finished in Radian’s gray Cerakote. Chambering in .223 Wylde lets shooters run both 5.56 NATO and .223 Remington ammunition through the same barrel with tight, accurate tolerances, making this upper a strong choice for a duty, competition, or range-precision AR-15 build. At 16 inches, the barrel clears the federal minimum length for a rifle-configured upper with no additional paperwork required.
