Has anyone here built a 80%-90% M4 lower with a Drillpress? I am thinking about getting a cross slide vise to use in milling w/ my drillpress w/ mill end bits. Can anyone give me some feedback on this idea?

Drill presses are not intended for side loading.
A vertical milling machine is.
I know and plan on drilling all the hole straight down and comeback with the cross slide and take a little off at a time. I wish that I had a Mill in my shop.
I'm interested in this topic as well.
Have you seen one of the many you tube videos on the process?
Looks like it works, although I'm not clear on the quality level of the finished lower.
I've seen guys drill away most of the material and then finish the cavity with files.
Not sure what quality this would turn out though.
If you do it right, you can have enough clearance for the trigger, and just leave the slight "wave" left from the holes over lapping.

MOVED SINCE THIS ISN'T A CUSTOM BUILD TOPIC.
Plunge cuts with an end mill would work to smooth out pocket.
It would take a lot of them, and a file would likely still be needed for the sides on the FCG cavity.
