What do you mean by ‘last one’? For bare aluminum you should be blasting with glass beads and that won’t do anything to deep engravings which is most factory engravings. Only shallow laser engravings and single pass spring loaded tools are potentially removed from blasting with coarse media.

It was that one. I purchased it before T91tactical had their 80%. I took it to someone for blasting and their were the ones that hit it with 100 grit after milling.

Blasting places vary. A place that does a lot of aluminum work will have the right media. Ask if they have glass bead media.

Marking is about 0.008" depth after sandblast, way deeper than the serial number 0.003".
