The Radian Weapons Model 1 Upper & Handguard Set is a premium, matched foundation for a long-range or competition-focused AR-15 build. Precision CNC-machined from 7075-T6 billet aluminum, this set features an exceptionally long 17 free-float M-LOK handguard, providing maximum rail space and a superior sight radius. Finished in a durable Radian Black Cerakote, the upper receiver comes pre-assembled with a dust cover, lightweight forward assist, and a specialized stainless steel anti-rotation pin. This high-performance kit also includes a 7075-T6 aluminum barrel nut, a proprietary wrench, and the suppressor-optimized Raptor-SD ambidextrous charging handle. Note: As an Upper & Handguard Set, this is a non-barreled assembly. To complete the build, you will need to provide your own barrel, gas system, bolt carrier group, and muzzle device.
