You can't just get a generic CNC program because the feeds, speeds, step overs, depths are all dependent on the tooling used. I guess someone could say here's a list of tools used but it wouldn't be the best way of going about it with all the different machines that are out there.
Tag for a print/model of the AR10. |

It's really very simple;
The main pocket is identical to an AR-15, and the rear shelf only differs in depth (0.530" instead of 0.630") Use AR-15 blueprints, but base everything off of the selector detent hole instead of the front pivot pin hole. I'm telling you to do it this way because the .308 AR lower is not a standard design, and some of the prints out there for completing them will leave you with an expensive paperweight. Those cncguns.com blueprints, for example, are NFG for Ares Armor billet lowers. Off by about 0.070", IIRC. |

sixtysixdeuce, going off of the selector detent hole on this print should be sufficient on an Ares (or any other) lower right? As long as all the FCG parts are aligned correctly I should be gtg? Yes. What you need to do is find center of the forward pin hole, just as you would with an AR-15. Then come back the amount indicated in the blueprint (6.138") and see if you are centered on the pre-drilled selector detent hole. If not, then you need to move all your dimensions forward or backward by the amount it is off. Like I said, I seem to recall it being ~0.070", which would have put the FCG pocket right through the mag release bore and left the selector horribly off, to the point that it would have hit the stops on the receiver before fully engaging. |
