Rear post issues

Review for
Tdi Arms Flip Up Backup Sights
I ordered two of these since they were in stock (one of them I got basically free because of optics bucks so why not). The front post seems fine but the rear post seems to have some QC issues. The metal piece that the apertures are on has the screw hole (the one it pivots around) imperfectly drilled on both of them so that it is at an angle, which results in a left/right shift of your zero when spinning it to change the aperture setting. One of them has this defect very mildy and is probably okay, the other one is very questionable, both of them have the defect in the same axis. The rear post also cants forward slightly instead of being vertical when flipped up, which is not too bad an issue just visually odd.
