I got a wrench from PFC Thomas too. Nice improvement over the Brownells one. More expensive, but works for both M14 and M1.
Look forward to seeing this gem. You are welcome to borrow any of my tools for accurization and such as you may require. Rasps, stones, die grinder, rheostat, etc. I am really looking forward to seeing this. You understand quality and are a bright guy. I bet you'll make a fine M14 smith. Awesome!!!!!
