The Radian Weapons Model 1 Complete Upper in .223 Wylde (brand part number R0466) is a fully assembled 14.5-inch upper finished in Flat Dark Earth, built from billet-machined 7075-T6 aluminum with a proprietary extended M-LOK handguard and integrated anti-rotation pin. Its match-grade 416R stainless steel barrel has a polished crown and feed ramps and ships threaded, running behind an enhanced black nitride M16 bolt carrier group, lightweight forward assist, and Radian’s suppressor-optimized Raptor-SD ambidextrous charging handle. This is an upper receiver assembly only, with no lower receiver included, so it is not itself a regulated firearm.

Frequently Asked Questions

Is this bare upper itself an NFA-regulated item? No. It is an upper receiver assembly with no lower receiver included, so it is not a regulated firearm on its own. Installing it on a shouldered, rifle-configured lower without a registered short-barreled rifle would require ATF Form 1 approval first.

Does this upper include a bolt carrier group? Yes, it ships with an enhanced black nitride M16-pattern bolt carrier group and lightweight forward assist installed.

Is this upper suppressor ready? The barrel ships threaded and the included Raptor-SD charging handle is suppressor optimized, though you will still need to confirm your muzzle device and suppressor mount separately.
