I had a friend who wanted to do a special engraving on his wife’s AR. Before anyone gets bent, he has his gunsmith license, and he pushed the button for the final engrave. The engrave came out good, although the quality of the image left something to be desired.
I made a Snapmark jig to do the engrave. The snap marks are at the same height as the area being engraved. It works very well, we did a lot of sample engraves, and a few final engraves as there was an area of the engraving that was difficult to get down to bare metal. We wound up doing 2 lowers, he messed up his Anniversary date. Yup he looked at it 20 times and we did 5 test engraves before moving to the final one.
