So, I'm interested in making a custom roll mark on an unmarked lower.  Anderson, PSA, and Spikes are all selling unmarked lowers.  I don't really want to spend $250+ to get it engraved - it would be a fraction of the price to have a nice laser cut stencil made.  Does anyone have any recommendations of what I can do to add a roll mark?  Is it something I could screen print?  I guess I could use something like alumahyde?  Thoughts?
