What would be the cost for 2 lines (11 characters and 8 characters including a comma)? Also, can the engraving be done on the front of the magwell? What is your turn around time and in what condition does the lower need to be?
I know this thread is a bit old, but do still offer NFA engraving on AR lowers? If so, how far disassembled do you need the lower? What is the turn around time? Can you engrave on the front of the magwell?
Juno charges $80 for up to 28 characters IIRC.
