Description
Product Overview
Experience match-grade precision and unmatched structural strength with the Radian Model 1 Complete Upper Receiver Assembly. Engineered as a matching semi-monolithic receiver set, this upper is CNC-machined from 7075-T6 billet aluminum and structurally reinforced in critical stress areas to eliminate receiver flex and maximize shot-to-shot consistency.
Outfitted with a match-grade 416R stainless steel barrel, every Radian Model 1 upper carries a guaranteed Sub-MOA accuracy guarantee when paired with Black Hills Match Grade ammunition. Complete with an Enhanced Black Nitride M16 Bolt Carrier Group, a lightweight forward assist, a Radian Raptor-SD™ suppressor-optimized charging handle, and a extended M-LOK handguard finished in durable Radian Cerakote, this upper represents the absolute pinnacle of AR-15 performance.
Assembly Lead Time & NFA Warning: Assembled to order with a current factory shipping lead time of 20 business days. Barrels under 16" (e.g., 9", 10.5", or un-pinned 14.5") are subject to NFA regulations when installed on standard rifle lower receivers. Dead Air KeyMo Muzzle Brakes will replace factory flash hiders where required by local state laws.

Frequently Asked Questions
What accuracy standard does Radian guarantee for the Model 1 upper?
Radian Weapons guarantees Sub-MOA precision when firing match-grade factory ammunition, specifically tuned and benchmarked using Black Hills Match Grade loads.
How does the Raptor-SD charging handle improve suppressor shooting?
The Raptor-SD features a ported shaft design that channels blowback gases down and away from the shooter's face during suppressed fire, reducing eyes watering and carbon buildup.
Can I request a different muzzle device than the Dead Air KeyMo Flash Hider?
Yes. While the Dead Air KeyMo Flash Hider is standard (or KeyMo Muzzle Brake where mandated by state law), SilencerCo ASR Flash Hiders and SilencerCo ASR Muzzle Brakes are available upon request.
Will this upper fit on standard mil-spec AR-15 lower receivers?
Yes. Although optimized for the Radian A-DAC lower receiver, the Model 1 upper receiver is machined to standard mil-spec pin locations and will fit standard AR-15 lower receivers.
