Has anyone here used one of these jigs?  I want to do build a 80% lower and the price is right for the jig.

Thanks
Jason

I am in the process of building one right now using the cnc jig.  So far everything is going pretty good.  The only sticking point I am running into is with excess metal on the lower receiver itself.  The holes on the jig all seem to line up pretty well.  I'll find out as soon as I start installing the trigger group and other pins and springs.  Just a couple of holes you have to free hand, can't use the jig for.

Which ones?

Where did you get your lower?
