Frequently Asked Questions
What lower receivers are compatible with the Radian Model 1 14.5" Upper?
The Radian Model 1 Upper is compatible with any standard mil-spec AR-15 lower receiver. Radian Weapons also manufactures their own billet lower receivers designed to pair perfectly with the Model 1 upper for a seamless fit, finish, and function — though any quality mil-spec lower will work reliably.
Can I shoot both .223 Remington and 5.56 NATO through the 223 Wylde chamber?
Yes. The 223 Wylde chamber is specifically designed to safely and accurately fire both .223 Remington and 5.56 NATO ammunition. It combines the tighter tolerances of a .223 Rem chamber for improved accuracy with the slightly larger leade of a 5.56 NATO chamber for safe use with higher-pressure mil-spec 5.56 loads.
Is a 14.5" barrel upper legal to own in California?
A 14.5" barrel upper receiver on its own is legal to purchase and own in California. However, if you intend to assemble it onto a complete rifle, the overall rifle configuration must comply with California's assault weapons regulations. A 14.5" barrel is also below the 16" minimum for rifles under the National Firearms Act (NFA), so the assembled firearm's barrel must have a permanently pinned and welded muzzle device to reach the 16" minimum — or be registered as an SBR. Always consult a local firearms attorney or licensed dealer for compliance guidance specific to your build.
