The Radian Weapons Model 1 Upper & Handguard Set is a premium, multi-caliber foundation for the AR-15 platform. Precision CNC-machined from 7075-T6 billet aluminum, it features a Radian Black Cerakote finish and structural reinforcement in critical areas. The set includes an 8.50 free-float M-LOK handguard with a stainless steel anti-rotation pin and four black-nitride coated steel cross bolts. This semi-complete assembly comes pre-installed with a lightweight forward assist, dust cover, and a suppressor-optimized Raptor-SD ambidextrous charging handle. Note: As a semi-complete Upper & Handguard Set, this is a non-barreled assembly and requires a barrel, gas system, bolt carrier group, and muzzle device to be fully operational.
