Overview
The Radian Weapons Model 1 Upper Receiver and Hand Guard Set is a stripped upper designed for builders looking to customize their AR-15 platform. With a 15.5-inch barrel length, it is optimized for a mid-length gas system, which helps in achieving a softer recoil impulse and reliable cycling. This setup is particularly well-suited for .223 Remington caliber builds, making it a solid choice for those aiming for a balance of maneuverability and performance.
