I have just finished my second lower receiver but I have a background in manual machining.
I used 80% billet receivers and the jig from Jagernaut Tactical since the receivers come anodized leaving only the FCB needing to be finished. I also did not utilize the initial drill jig designed to remove the mass of the metal from the FCB. I center drilled a couple spots then drilled the mass out leaving about .030" at bottom to finish with the endmill.
To the point of using a drill press to finsih these off: if I were going to assist family/friends and didnt have access to a fullsize vertical mill I would purchase a smaller benchtop mill (around $1,000.00). While I am certain these could be completed with a drillpress the quality of work isnt going to be the same and it will take you far longer. I would also purchase two flute endmills instead of 4 flute endmills - 2 flutes work better on softer materials.
Now if I could find a 80% billet upper...
