    So, I took the chance and ordered a blemished completed upper from the folks at CBC Industries. I’m a skeptic and a perfectionist and expected to find many things I did not like. Let’s just say that’s not how it worked out. I scoured this thing.I mean every centimeter. If there’s a cosmetic blemish, I couldn’t find it. So I took it apart. No worries CBC. This is far from my first rodeo. Still no song of a blemish. Fitted it to three different lowers. No fitment issues whatsoever on any of them. Fully installed it on its intended lower and fired 600 rounds through it. Guys, buy this thing. Buy it now. Buy two. You WILL NOT be disappointed. These guys did a great job, from customer service to assembly to delivery, all top notch. Great job CBC.
