Product Description

The Radical Firearms 5.56mm complete upper assembly is a MIL-STD AR-15 upper designed to drop onto any MIL-STD lower receiver, making it a strong choice for finishing a new build or upgrading an existing rifle. It features a 16" Socom-profile barrel with a 1:7 twist and a free-float M-LOK handguard to support accuracy and accessory mounting while helping keep hands cooler during extended range sessions. Built around a forged 7075-T6 upper receiver with Type III anodizing, this upper includes a nitride bolt carrier group and a Mil-Spec charging handle, along with a forward assist and dust cover for a complete, ready-to-run setup.
