Radian Weapons R0193 Model 1 Upper & Handguard Set Multi-Caliber 7075-T6 Aluminum Radian Black Cerakote Receiver, 15.50" Magpul M-LOK Handguard for AR-15

The Radian Weapons R0193 Model 1 Upper & Handguard Set Multi-Caliber represents purpose-built precision engineering for AR-15 platform shooters who demand reliability without compromise. Designed for tactical professionals, competitive shooters, and dedicated enthusiasts, this upper receiver assembly eliminates the guesswork of component sourcing by combining a matched receiver and handguard in one coherent system. Whether you're building a duty rifle, a precision carbine, or a multi-role platform, the R0193 delivers the foundation needed for consistent performance across diverse shooting applications and caliber conversions.

Manufactured from 7075-T6 aluminum, the receiver exhibits exceptional strength-to-weight characteristics while maintaining dimensional stability under sustained firing and thermal cycling. The Radian Black Cerakote finish provides superior corrosion resistance and durability compared to standard anodize, essential for field environments and long-term storage. The integrated 15.50" Magpul M-LOK handguard offers modern ergonomic mounting flexibility, allowing rapid accessory reconfiguration for optics, lights, vertical grips, and tactical devices without tools or permanent modifications. This multi-caliber design accommodates upper receiver swaps across common AR-15 caliber families, giving you platform versatility with a single, precision-machined lower receiver investment.

Law enforcement armourers, military-style shooters, and builders seeking quality OEM components will find the R0193 compatible with standard AR-15 lower receivers and bolt carrier groups. The matched upper and handguard pairing ensures proper rail indexing and eliminates fitment variables common to mixed-component builds. At 3.15 lbs, the assembly strikes a balance between structural integrity and maneuverability—critical for tactical carbines where every ounce affects weapon handling during extended operations. Installation requires no special tools; standard pivot pin and takedown pin removal integrates the upper onto any mil-spec AR-15 lower in seconds, making this set ideal for modular rifle development or field replacement scenarios.
