The Radian model 1 upper receiver and hand guard are meticulously CNC machined to complement each other perfectly, with strategic reinforcements in critical areas for added strength and durability. Crafted from billet 7075-T6 aluminum, the upper receiver is equipped with essential components including a dust cover, hand guard anti-rotation pin, lightweight forward assist and the Raptor-SD ambidextrous charging handle. The hand guard features Magpul M-LOK slots for versatile accessory attachment, secured to the barrel nut with four black nitride-coated steel cross-bolts to resist corrosion. Every surface undergoes precise machining and chamfering to ensure a smooth, ergonomic profile free of sharp edges. Finally, both components receive a matching Radian Cerakote finish for a seamless appearance.

These items are controlled by the U.S. Government and authorized for export only to the country of ultimate destination for use by the ultimate consignee or end-user(s) herein identified. They may not be resold, transferred, or otherwise disposed of, to any other country or to any person other than the authorized ultimate consignee or end-user(s), either in their original form or after being incorporated into other items, without first obtaining approval from the U.S. government or as otherwise authorized by U.S. law and regulations.

Local Law Compliance

Certain firearm parts and accessories, including AR-style upper receivers, are subject to complex and frequently changing federal, state, and local laws and regulations. While an upper receiver may be lawfully sold and shipped as a component, the legality of possessing, assembling, configuring, or using an upper receiver in certain states (e.g., California, Washington State) and localities depends on how it is assembled, combined with other components, and ultimately used. You are solely responsible for ensuring that any assembly, configuration, possession, or use complies with all federal, state, and local laws, including any so-called “assault weapon” bans and short-barreled rifle restrictions. We do not provide legal advice and are not responsible for unlawful configurations or uses.
