Some concerns were raised about my purchase of a PSA BCG in this post. I figured I'd add this information for any questions/concerns. To be clear, this is in regards to the PSA Premium BCG with no logo, not their bottom-of-the-bucket PTAC line which makes no claim to being HPT/MPI.
The BCGs arrived covered in a very thick preservative. Here's a picture of them after cleaning them off....clearly marked HPT/MPI bolts. The gas key appears to be decently staked. The bolts came with black o-rings installed.
