A bit back, my friends at the Hacker Consortium got themselves a laser engraver/cutter similar to this one
So I did what any rational person would do. I took several magazines to get the GCT Logo engraved on them!

I did one M&P15-22 mag, a Glock Fun Stick, and a seriously used aluminium AR mag. Results were kind of “meh” because my expectations were high. Still pretty cool, though!
