Radian Weapons R0428 Model 1 Builder Kit AR-15 10" M-LOK Handguard - Radian Gray

The Radian Weapons Model 1 Builder Kit bundles the premium upper-and-lower foundation of Radian's flagship ambidextrous AR-15 platform into a single package, finished in Radian Gray and assembled around a 10" Magpul M-LOK handguard. Built around the same components used in Radian's factory rifles, this kit provides custom builders the brand's signature billet upper, serialized AX556 lower receiver, and ambidextrous controls as a refined starting point for a custom build.

At the heart of the kit is a precision-machined billet upper receiver pre-fitted with an installed dust cover, anti-rotation pin, and lightweight forward assist. The matched handguard carries a Magpul M-LOK accessory mounting system and is secured with the included cross bolts, washers, and nuts. The platform is chambered to support both 5.56 NATO and .223 Remington.

The Model 1 is distinguished by Radian's full ambidextrous control suite, including the Raptor-SD charging handle and Talon ambidextrous safety selector, giving both right- and left-handed shooters complete, equal access to the manual controls. Sights are not included. Combined with the included serialized components, this builder kit delivers all of Radian's premium hardware needed to assemble a feature-rich, fully ambidextrous AR-15 around your preferred barrel, bolt carrier group, and furniture.
