A friend of mine has a Diamondback AR-15. As far as I know it is like nearly everything else, mil-spec parts, etc. He had a problem with it not cycling properly after a few dozen rounds. I looked it over for him and found that the gas rings on the bolt had worn out. I don't blame that on any brand as I had one that did the same thing after less than a hundred rounds and I built it with a quality LPK. They are a wear part, some last longer than others. Proper lubrication solves a lot of problems with ARs. I haven't shot his rifle but for a budget AR, I think it is fine.
