Poor overall quality and finish - TRYBE Defense AR-15 5.56x45mm NATO Upper Receiver

I bought this item to pair with a PSA lower thinking I would save a few dollars and buy a quality optic with the savings. Little did I know that the Trybe Defense complete upper receiver would be lack luster to say the least. The finish on the MLOK railing is so poor that I can permanently scratch it with my fingernail. Underneath the MLOK railings were several metal shavings. The old adage of you get what you pay for maybe true in this case. I cannot believe that this was a deliberate quality issue. Must have been a QA/QC problem of the whole lot. If I would have paid 225 for it, I would expect such a rough finish but 325 out the door is too much especially with many other options available. BLUF, Trybe Defense should be embarrassed for allowing these to leave the factory.
