What indicated to you that it's a hack job?
I didn't get that impression from the ad. I would just want to know how the gas block was removed, because it has some telltale signs of being either an AA low profile block or an FSB before.
The upper has the correct AA markings on it.
The BCG looks like it has seen some use as the carrier rails are worn and the lug I can see looks worn.
There is no "new SAAMI spec".
