I've read a lot of good things about their ARs, even after CD went out of business. Corners weren't cut, the quality was very close to Colt, BCM, Daniel Defense, Noveske and LMT. If you come across a good deal I wouldn't be afraid of it.
Also, a few years ago I bought a CD stripped lower for my son-in-law. It was made in Harrisburg, PA, his hometown. Beautifully finished lower with a flared magwell. No issues at all with the build.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
