The Radical Firearms AR-15 upper receiver assembly comes ready out of the box to attach to any Mil-Spec lower receiver. It has a forged M4 railed upper, so you can easily attach scopes and red dot sights to the MIL-STD rail. The upper receiver includes the bolt carrier group, MIL-STD charging handle, ejection port cover, and forward assist. The barrel is 16" of 4140 Chromoly steel with a Melonite coating and is attached via a steel barrel nut. The barrel has a 1:7 twist, designed to stabilize heavier 556 NATO and 223 Remington ammo at intermediate ranges. This twist rate will still stabilize standard 55-grain FMJ ammo as well, so your range time won't be affected by not being able to find 62 grain Gold Dots. Attached to the heavy SOCOM profile barrel is an A2 flash hider. This complete upper receiver is an excellent addition to your AR-15 build.
