I have owned WC barrels in 6.8 and 5.56. They are both quality barrels and get the job done. I had an issue with a barrel (due to my reloading) and WC still helped me with the issue. Their customer service was top-notch. I have used Aero Precision parts before, too. The uppers and lowers are high-quality in my book.
Take your time with one build and learn from others. It seems so easy to slap an AR together but its the technique that you use which ultimately leads to a "quality build."
Example 1: stretching the threads on the upper receiver.
Example 2: gas-block alignment.
