They have a teflon coating that makes them look pretty. It does nothing as far as protection or function. It is not spec either.

OMG, not to spec...
Well if the teflon does nothing to help function then I guess they just function 100% because they are made well.
They are hard coat anadozied (spec) then teflon coated IIRC.
The machining marks I was referring to were just like the past Bushy thread that showed all the material left on the front of the magwell etc. They are not something that a coating, any coating, would cover up.

The teflon coating does nothing for the funtioning
of the durablity of the finish on the lower. It is there to look pretty.
One may have thought teflon was a durable finish. It is, but it is not as tough as Type III anodizing. Any impact that will scratch, ding, or damage the anodzing will go right through the teflon as it is less hard than the anodizing.
Anodizing is really aluminum oxide, the stuff sandpaper is made from.
