RADIAN WEAPONS Model 1 Builder Kit Billet Upper/Lower Set w/ 10in MLOK Handguard (R0427)

The Radian MODEL 1 BUILDER KIT is the perfect starting point for your next build and allows for ultimate customization and personalization. The A-DAC 15 lower receiver is machined from billet 7075-T6 aluminum and is a fully ambidextrous lower receiver. In addition to the Talon Ambidextrous Safety Selector, left-side magazine release, and right-side bolt release, the A-DAC 15 features the patented A-DAC (Ambidextrous Dual Action Catch), which allows right-handed shooters to easily lock the bolt to the rear without taking their hand off fire control. To hold the bolt back using the A-DAC, simply pull the charging handle to the rear, depress the right-side magazine release button, then release the charging handle.

The Radian Model 1 Upper Receiver and Hand Guard are precision CNC machined as a matching set, structurally reinforced in critical areas for improved strength and rigidity. The upper receiver is cut from billet 7075-T6 aluminum and assembled with dust cover, hand guard anti-rotation pin, light weight forward assist, and Raptor-SD Ambidextrous Charging Handle. The hand guard features Magpul® M-LOK accessory mounting slots that attach to the barrel nut using four steel cross bolts coated in black nitride for corrosion resistance. Every surface has been precision machined and chamfered to ensure no uncomfortable, sharp edges can be found. The upper and hand guard are then sprayed with Radian Cerakote options for a perfectly matching finish.
