Radian Weapons R0414 Model 1 Builder Kit AR-15 14" M-LOK Handguard - FDE

The Radian Weapons Model 1 Builder Kit (R0414) is a premium matched upper/lower receiver builder set designed to anchor a high-end AR-15 platform build. Radian's billet-machined upper and lower receivers wear a durable Cerakote Flat Dark Earth finish that carries across the handguard for a clean, unified appearance.

The upper ships fully assembled with a matched dust cover, anti-rotation pin, and lightweight forward assist already installed. Attached to the upper is a 14-inch free-float handguard built around the Magpul M-LOK modular attachment interface, giving the builder a slim, lightweight platform for accessories, optics mounts, and sling attachment points without unnecessary bulk.

Radian's signature ambidextrous controls come standard in this kit, including the Raptor-SD ambidextrous charging handle, the Radian Talon 45/90 ambidextrous safety selector, and an ambidextrous bolt catch. Intended for a semi-automatic build chambered in 223 Remington / 5.56 NATO, the Model 1 Builder Kit provides a turnkey foundation for assembling a top-tier rifle from the ground up.
