Upper And Hand Guard Set

The Radian Upper and Hand Guard Set is a precision-engineered matched component system designed for operators and builders who demand uncompromising accuracy and structural integrity in their AR-platform rifles. Built as a cohesive unit rather than separate aftermarket components, this upper receiver and integrated hand guard combination addresses a critical weakness in many factory and assembled builds: mechanical instability caused by tolerance stack-up between upper and rail interfaces. Whether you're outfitting a duty rifle, precision carbine, or competition platform, the matched design eliminates the guesswork and potential for zero shift caused by component misalignment.

The upper receiver is precision CNC machined from billet 7075-T6 aluminum—the gold standard for structural rigidity in firearms manufacturing—and reinforced at critical stress points including the charging handle lugs, optic rail interface, and bolt carrier key contact areas. The integrated hand guard is engineered to eliminate rotational play through dedicated anti-rotation pinning, a feature that minimizes torque transmission to the barrel extension and maintains consistent poi (point of impact) across shooting sequences. This matched-set approach reduces overall system deflection and improves repeatability, particularly under rapid fire or sustained use where heat and barrel whip can compromise zero stability. The assembly weighs 3.5 lbs and measures 33 inches in length, fitting standard AR receiver extensions and compatible with mil-spec components throughout the build platform.

Law enforcement patrol rifles, mil-sim competitors, and serious builders benefit most from this platform when tolerances matter and zero retention is non-negotiable. The matched receiver and hand guard design simplifies installation for gunsmiths and experienced builders, eliminating the need to source and test separate upper and rail components. Installation requires standard AR-15 assembly tools and familiarity with receiver extension torque specifications and gas tube routing. This set integrates seamlessly with mil-spec bolt carrier groups, charging handles, and dust covers, making it an ideal foundation for custom builds where accuracy and durability cannot be compromised.
