Radian Weapons R0403 Model 1 Builder Kit AR-15 15.5" M-LOK Handguard - Radian Black

The Radian Weapons Model 1 Builder Kit is a premium AR-15 upper assembly package built around a precision billet upper receiver with a factory-installed dust cover, anti-rotation pin, and lightweight forward assist. This kit (MPN: R0403) gives builders a complete upper-end foundation for a high-end 5.56 NATO/223 Remington AR-15 platform.

The centerpiece is the 15.5 inch Magpul M-LOK handguard finished in Radian Black, providing a free-float platform with the modular M-LOK attachment interface for accessories, lights, and optics mounting. Radian's signature ambidextrous controls are all part of the package: the Raptor-SD ambidextrous charging handle for left- and right-side manipulation, the Talon 45/90 ambidextrous safety selector configurable for short-throw or long-throw operation, and an ambidextrous bolt catch for full left-hand control of the action.

Designed around the AR-15 platform, the Model 1 Builder Kit is intended for the shooter building a premium AR-15 upper with Radian's renowned fit, finish, and fully ambidextrous feature set.
