Radian Weapons has earned a reputation for being one of the best firearm parts and accessories manufacturers in the U.S. The company is known for creating some of the most accurate and reliable AR-15 upper assemblies around. If you’re building a high-end AR-15, the Radian Model 1 Upper is an excellent option. This .223 Wylde complete upper includes a high-end barrel, a modern modular handguard, an upper receiver with a bolt carrier group, and a charging handle.

Precision Match-Grade Barrel

The Radian Model 1 Upper is made with precision and quality craftsmanship to provide you and your AR-15 with sub-MOA accuracy. It comes with a 16-inch match-grade barrel constructed out of 416R stainless steel. This barrel has a polished crown and a 1:8 twist rifling to ensure supreme accuracy. To improve reliability, the barrel extension also has M4 feed ramps.

In any modern rifle, mounting muzzle devices is essential, and this .223 Wylde complete upper definitely delivers in this department. Its barrel is threaded and has the popular 1/2-28 thread pitch. It also comes equipped with a Dead Air flash hider to boot.

Modern Modular Handguard

In addition to its match-grade barrel, the Radian Model 1 Upper includes a proprietary extended aluminum M-LOK handguard. This handguard has M-LOK slots at 3, 6, and 9 o’clock, and on top, it features a continuous Picatinny rail for mounting sights and optics. You’ll be able to get a firm and comfortable grip on the handguard thanks to its design, and it even has a stainless steel anti-rotation pin to keep it securely attached to your firearm’s receiver. The gas system on this upper is impressive, too, with its low profile and its mid-length gas tube that will make your gun smoother and more reliable than it would be otherwise.

High-End and Ambidextrous

This upper receiver is made from billet machined 7075-T6 aluminum and features a unique Radian finish. You’ll also love the .223 Wylde chamber, making it possible to fire both .223 Remington and 5.56 NATO ammunition safely. The M4 feed ramps are a nice touch as well, as they’ll feed ammo into the chamber of your firearm reliably, and you’ll get access to features like forward assist, case deflector, and a port door with this upper.

Regarding the bolt carrier group, the Radian Model 1 Upper comes with a Radian Enhanced Black Nitride M16 Bolt Carrier Group. This BCG is made from high-quality materials that will make it last and meet your expectations. Last but certainly not least, this upper has a Radian Raptor-SD Charging Handle, an ambidextrous charging handle designed to work well under heavier pressures when you’re shooting suppressed.
