And yes, I'll be machining it myself

My lower was made by Ares Armor, I'd love to get those files if you don't mind!

I have a DPMS 80% lower that I'm looking to drill out (or get some help drilling out for anyone in the San Diego area). I have access to a CNC machine but I don't have the files or program required to do it. Does anyone here have advice on this?

If you get your hands on a CNC there are files you can use (someone on this site has them I'm sure) where it will drill it out perfectly. Also, there is a couple places around San Diego that do "Machine Rentals" where you take your 80% and they walk you through how to do it. I'm still looking for the right people to do this with. Actually I have access to a CNC but I don't have the files.
