Radian Weapons Builder Kit, 15.5 Inch M-LOK Handguard

Description

This Radian Weapons builder kit is listed as a semi-complete AR-15 receiver package with a multi-caliber configuration and a 15.5 inch M-LOK handguard. The package includes a billet aluminum upper receiver, an AX556 lower receiver, and a Raptor SD charging handle. We see it as a component-focused option for builders who want the principal receiver and handguard components together.

The matching upper receiver and handguard are described as precision CNC machined components with reinforcement in selected areas. The handguard attaches to its barrel nut with four steel cross bolts finished in black nitride, while the M-LOK interface provides a standardized way to mount compatible accessories. Its semi-complete format leaves the remaining build configuration to the purchaser. We stock this kit for builders who want the AX556 lower, billet upper, and handguard assembled as a coordinated component set.
