Poor condition - SIG SAUER Sig MCX Upper Receiver Assemebly, M-LOK

I received this upper today. The upper is dirty from use with scuffs, wear. The spot where the rear pin goes through to connect the upper to the lower looks like it was hit on something very hard or possibly with a hammer. I was under the impression this was to be new and in good condition. Going to have it assessed by a gunsmith and probably returning it.
