The Radian Weapons complete upper receiver in 223 Wylde is a purpose-built, ready-to-run upper assembly designed for shooters who want quality components assembled and tested before they arrive. Built on a 17.5" barrel with a 1:8 twist rate, this upper pairs versatility with precision — the 223 Wylde chamber shoots both standard 5.56 NATO and commercial .223 Remington loads with tight chamber tolerances that favor accuracy. This is a genuine bolt-on solution for AR-15 platforms: unbox it, mount it to a compatible lower receiver, and you're ready for the range or field.

Radian Weapons engineered this assembly with execution in mind. The 17" M-LOK handguard gives you real estate for accessories and a comfortable grip zone that doesn't overheat on strings of fire. The Radian Raptor-SD charging handle is their signature ambidextrous design, engineered for smooth operation and durability. A Dead Air KeyMo flash hider manages muzzle signature and allows quick mounting of compatible suppressors. The enhanced bolt carrier group and Cerakote finish reflect Radian's attention to both performance and longevity in hard use.

The intermediate-length gas system keeps recoil manageable and pairs logically with a 17.5" platform — neither overgassed nor undergassed. This upper works equally well as a mid-range tack driver, a 3-gun stage gun, or a versatile home defense or hunting upper once you pair it with the right lower and ammunition. Whether you're building from scratch or upgrading an existing rifle, a matched upper like this removes guesswork and gives you a platform proven by Radian's reputation for quality control.
