"Just as Good" AR Parts - Exhibit #1

Nitride AR BCG's are a constant problem with them being out of spec.

So the NO-GO went... so the port is over sized. Would the Nitride generally make it under sized? Or did they over compensate for the coating and missed the target?

Thanks for the continuing education...

The Nitride is normally oversize which means gas leakage.

The companies who use Nitride are likely sourcing parts that were destined to be chrome lined. This means when Chromed they are in spec, but if Nitrided they are oversize since Nitride isn't a coating, just a surface treatment.

When I saw the thread title. I thought that you were going to be talking about the pistol parts I brought to class Saturday ... or at least the gas block.
