I can't speak for DPMS or PSA, but I bought a Diamondback upper after having terrible accuracy with my BCA Grendel upper. The Diamondback did shoot better, but still wasn't anywhere near acceptable. I wouldn't be surprised if they used BCA barrels but I don't know that for a fact. It does shoot but who wants a gun that isn't very accurate. Luckily, many of those other calibers don't seem to be as difficult to make accurate barrels for. I've never had bad accuracy with any of my other budget build guns in the various calibers until I tried it with a Grendel, and then it was two for two failed.
