Radical Upper 556 NATO Complete Assembly

This complete upper receiver assembly delivers the reliability and performance serious shooters demand. Built with quality components and thoughtful engineering, it's ready to mount on your lower receiver and get to work.

Key Features

  • Barrel: 16" chrome moly vanadium with nitride finish for superior corrosion resistance and durability
  • Twist Rate: 1:7 for excellent stability across a wide range of 5.56 NATO ammunition weights
  • Handguard: 15" RPR M-LOK rail system provides ample real estate for mounting optics, lights, and other accessories
  • Muzzle Device: A2 flash hider reduces muzzle signature and flash
  • Finish: Nitride coating protects against wear and corrosion

Why This Upper Works

The 16" barrel length balances velocity, handling, and portability—a proven configuration for both tactical applications and general shooting. The M-LOK system has become the standard for modern rifle platforms, offering lightweight modularity without the bulk of older designs. The 1:7 twist rate handles everything from lighter 55-grain rounds to heavier match ammunition with equal competence.

Whether you're building a patrol rifle, a competition platform, or a reliable all-purpose 5.56, this upper assembly provides the foundation for a capable rifle.
