These do not fit with sharps lowers, very sloppy fitmemt - Sharps Bros. Upper Receiver Ar-15 Billet W/dust Cover

I have a jack lower and I’ve tried every size pivot and take down pin and it wobbles around like crazy. Now I’ve been trying to find an upper for the sharps jack lower to fit and I’ve tried 7 brands so far the the lower is a super loose sloppy blade fit. Sharps is a fad and I would never buy their lowers again only cause they look cool. Do not buy unless you Like super loose fitment from the lower to the upper. Also you can use an accuwedge but I don’t prefer adding plastic in my lower. Never gonna buy a sharps lower again. The holes are supposed to be mil spec on the lower but they are much larger. John Sharp the owner doesn’t care. Terrible customer service from him.
