Not as advertized - SIG SAUER MCX 5.56 Nato Upper Receiver

This is an indifferent review. I cannot write a review for this product because the one i received did not have anything but the upper. No trigger or adapters. I caj that the stock virtus trigger is good, but not a G. The 11.5 itself is a good upper runs well, but, but not with low powered 223.
