Scorch: Ok I think I found the piloted bits you were talking about. They are the ones with a smaller diameter at the tip that then steps up to a larger diameter correct? Why would the drill press not be able to do the job though?

Gunplummer: I think the DPMS barrel I was looking at may be chrome lined.

(it's the 14.4" at the bottom of the list.)

Brownells and other retailers don't mention chrome lining, but it says chrome lined on DPMS website. Is it going to be impossible to drill or will I just need a harder tool?

Edit: I'll probably just go with a Del-Ton barrel since I can be sure that it's not chrome lined and it costs about $30 less than the DPMS. Would have liked to keep all the same manufacturer's parts on my rifle though but oh well.
