Radian Weapons 14.5" 6mm ARC Complete Upper Receiver – AR-15 Platform (Grey)

The Radian Weapons 14.5" 6mm ARC upper receiver assembly delivers extended-range precision in a compact AR-15 platform configuration. Chambered in 6mm ARC, this upper offers superior ballistic performance compared to standard 5.56 NATO, with improved wind deflection and energy retention at distance. The 14.5" barrel length balances velocity with maneuverability, making it well-suited for precision work where portability matters.

Manufactured with Radian's signature attention to detail, this complete upper features a grey anodized finish and includes the barrel, gas system, handguard, and charging handle. The upper is built on a mil-spec forged receiver and installs on any mil-spec AR-15 lower receiver. Note that 6mm ARC requires compatible bolt carrier groups and magazines designed for the cartridge—standard 5.56 BCGs and magazines will not function properly.
