The EZ-Set hole for detent installation is excellent! If I have to pull the Pivot/Takedown pins on any of my lowers I'm probably going to replace them with the Armaspec enhanced pins.
The titanium pins fit perfectly/tight in my Aero lower, and a little loose in the PSA lower.
The colored Superlight pins are painted/coated and fit tight in the PSA lower. I suspect the PSA lowers have slightly loser tolerances (fatter holes) to allow for broader compatibility.
So for tighter applications, such as Aero lowers, you probably want to get unpainted pins. For the Superlight pins, I suspect that black and silver are uncoated or coated in a manner that doesn't increase the diameter as much.
