Precision. When properly set up, there is no need for "tolerances". CNC will crank out same size part every time (if bits are cared for/new).

You input some instructions, putting a chunk of steel from one side, and gun parts coming out from other side?

Pretty much. High cutting speed; low amount of cut; unattended operation. Roderus has an interesting (but long) thread of a guy who CNC'd his own AR-15 lower receiver from a chunk of aluminum...

CNC workstation costs as much as a small house...and it requires CAD/CAM knowledge to code programs...

I don't have $$$ or knowledge...too old; too poor...

I have no money either, and worse, don't know how to code my TV remote. But it's good to know. Thanks!

Your Community College or BOCES might offer programs on CAD/CAM...big drawback is getting time on the workcenter...they cost so much that the shops owning them must keep them in operation full-time to recoup their money...

A place where CNC guys hang out and share projects/ask questions is -

http://www.cncguns.com/forum/index.php

...and they have some CAD programs already worked out...

Roderus is more garage-workshop guys (ex. Bridgeport Mill, South Bend Lathe) where CNCGuns is...well, CNC workcenters...but CNCGuns also has many smaller workshop guys (like me!) too...
