Probably not worth the trouble - Armaspec Superlight Takedown Pivot Pins Package

The finish matches my FDE receiver perfectly and they are very light, but they are too tight. It seems I will have to sand away the coating completely on the pins to make them fit, and that's not worth the trouble in my opinion. A spare standard takedown pin I had layout around fits the same receiver without issue and I will likely just go back to those.
