Last spring I got a Daniel Defense complete rifle, new. I started freaking out because I noticed what appeared to be some odd wear in the pivot pin/takedown pin holes. DD customer service told me (and others who asked them about the same thing) that they hone out the holes a bit after anodizing to ensure a good mating of the upper and lower receivers. At the time I was afraid of the honed off anodizing causing premature wear of the pivot pin holes, where the steel pins would eventually "egg out" the holes to the point of making both receivers unusable.
Some here raised a stink, saying my concerns were valid, while most others said it was nothing. I ended up selling it off. Here I am a year later, thinking about how nice that DD was other than that one thing... and now I'm wondering if I really was freaking out over nothing. (I'd also like to say that DD's customer service was exemplary and makes me want to try them again).
Would this concern you at all from a longevity standpoint? Here are some pics I took back then.
