Radian Weapons 6mm ARC 14.5" Complete Upper Receiver Brown

Radian Weapons does not build budget parts, and it shows in this complete 14.5 inch 6mm ARC upper. Receiver machining, coating quality, and component fit all sit at the top of the AR market, which matters more on a precision leaning cartridge than it does on a blaster build.

6mm ARC gives a compact gun real reach: flatter trajectory, better wind performance, and more retained energy than 5.56 from comparable barrel lengths, which is why the cartridge has pulled in both hog hunters and long range AR shooters. The brown finish sets it off from the usual black and FDE crowd. Mount it to a standard AR-15 lower and the hard part of the build is already done.
