I posted a picture of an engraved NDS receiver and Brick moderator in another thread yesterday and have had a few PM's asking about them. They were all done by Ident Marking a year or two ago. They are holding up well, but if a lot of CLP is used the color fill will fade. A little alumi black (even though the receivers are grey) refills them. Just painting it in the engraving, let it sit for a few seconds, wiping off, retores them. Don't let it remain on too long or you can darken the grey anodizing where it touches.
This is the photo I sent and the result:

Here is another receiver done a little different:
Here are two of the rifles and the carbines the receivers are on:
