These are genuine
Diemaco C8 uppers (with the D on them), fixed carry handle with 14.5"
5.56 NATO barrels. They do have wear on them...they have been issued
so don't expect a new one. The bores look good on all of them ones I
have looked at. We don't cherry pick these for people so please don't
ask. The picture is of actual uppers from the shipment.
