Frequently Asked Questions

What is the advantage of a 223 Wylde chamber over standard .223 or 5.56 NATO?

The 223 Wylde chamber is a hybrid design engineered to safely and accurately fire both commercial .223 Remington and military 5.56 NATO ammunition. It uses the leade angle of the 5.56 NATO chamber for safe pressure management with hotter military loads, while maintaining the tighter chamber tolerances of .223 Remington for enhanced accuracy. This gives shooters the flexibility of running a wide range of factory loads without sacrificing precision.

Will this upper fit my existing AR-15 lower receiver?

Yes. The Radian Model 1 upper is designed to mate with any standard mil-spec AR-15 lower receiver. Simply pin your existing lower to this complete upper and you're ready to shoot. No special tools or modifications are required for the upper-to-lower fit, though Radian recommends pairing it with a quality mil-spec lower for the best overall experience.

What makes the Radian Model 1 worth the premium price compared to other complete uppers?

Radian Weapons sets itself apart through the use of billet 7075-T6 aluminum (stronger and more precisely machined than forged receivers), fully ambidextrous controls, and individual hand-assembly by a certified gunsmith who personally inspects and test-fires each unit. Add to that a Sub-MOA accuracy guarantee and a lifetime warranty, and the Model 1 offers a level of accountability and craftsmanship that most production uppers simply cannot match.
