I had zero issues with my shipment and got it fast, but I have only made one purchase.
ETA: After further review I see some issues.
So, you got the Nickle Boron BCG and such, right? You traded that for your chrome-moly barrel.
Not sure which you prefer, but your purchase was with a chrom moly vanadiun barrel. The one you received is 4150V.
I don't know enough to say which is best. The one you ordered was melonite finished, the one your received is nitride finished. If I recall, both are nitrocarburized processes. Once more, not enough experience to say which is best. But you are getting different build materials.
