Does anyone know of a model or blueprint set for a DPMS style LR-308 lower receiver or upper for that matter? One of the projects I would really love to try with a CNC machine is to make my own .308 upper and lower. I have seen solid models of the AR-10 design but I already have a DPMS SASS and I don't want another type of .308 magazine to stock. I know there are some nice 80% lowers out there but this is mostly an exercise in fun so I want to try starting at a solid block. Of course doing the mag-well could be a great big fly in that ointment for that plan.
