I'm not saying it's right or wrong, but this review states it can take any mil-spec upper available. We all know anybody can be mistaken, but all the reviews I've read on it point towards any of them working. It does, however, need to change out the recoil system for the .308 vs. .223/5.56. I haven't been able to find any just lowers and adapter yet, but hopefully we'll be able to in the future. It sounds to me as though the .308 upper is proprietary though. But on a good note, the lower is all ambidextrous.
