Solid upper for some - Aero Precision M4E1 5.56 NATO No Forward Assist Enhanced Upper Receiver

First, it's an upper, and it seems to be in spec. So there isn't a ton to say beyond the hand guard attachment. I like the thought of offloading the stress of the hand guard off of the barrel nut and on to the upper frame. Does it change anything? I have no clue. I had one of the enhanced hand guard from another build, so this made sense for me. The styling is good. It mates up to my lower with almost no gaps and there is zero movement between the upper and lower when pinned.
