Just a regular 5.56mm lower? Quentin Defense, Dlask, YellowLogic, Tactical Machining, AR15Jigs or AR15Plus. Yellow logic also has dedicated 9mm Sten or C Products lowers. Tactical Machining does .308 lowers.

I used to manufacture lowers for both 15s & 10s. I have since went on to more lucrative millitary products. I can't tell you what kind of result u will have with a drill press. That souds like quite the challenge, if you really want to make a quallity firearm . If u need any help.... I am not far from you.

If you can not get excited and take very small bites, it is doable with a drill press with a good jig

I will be using a tactical machining jig soon, but you can't go wrong with the cncguns jig either. I like the CNC jig for its plate that tells you where to drill to remove the bulk of the material, but I don't like the price nor the lower bottom that requires spacers to fit on the table.
