Radian Model 1 Complete Ar15 - Upper 223 Wylde 17.5" Fde

The Radian Model 1 Complete AR15 Upper in .223 Wylde with 17.5" barrel is purpose-built for shooters who demand precision, reliability, and modularity in a mid-length platform. This complete upper receiver assembly is ideal for law enforcement, military, and civilian marksmen seeking a versatile rifle system that bridges the gap between tactical carbine performance and inherent accuracy. The .223 Wylde chamber chambers both 5.56 NATO and .223 Remington ammunition, providing maximum ammunition compatibility without sacrificing precision—a critical advantage in field operations where supply chains vary.

Radian's Model 1 upper features a 17.5" barrel length that optimizes velocity, sight radius, and handling weight for both close-quarters and intermediate-distance engagements. The mid-length gas system ensures reliable cycling across diverse ammunition loads while reducing bolt carrier group wear compared to carbine-length systems. Finished in Flat Dark Earth (FDE), this complete upper integrates a precision-machined upper receiver, bolt carrier group, and charging handle in a unified assembly ready for immediate installation onto any mil-spec lower receiver. The FDE coating provides corrosion resistance and reduces glint in operational environments while maintaining professional aesthetics.

This upper assembly is compatible with any standard AR15 lower receiver featuring a mil-spec trigger group and magazine well, making it an excellent upgrade path for existing rifle platforms or the foundation for a new build. Installation requires no gunsmithing—simply mate the upper to a compatible lower, secure the takedown pins, and function-check the charging handle travel. Law enforcement armorers appreciate the Radian Model 1 for its robust design and straightforward maintenance access, while competitive shooters and duty-rated operators rely on its inherent accuracy and proven reliability across extended training cycles and operational use.
