I've been scouring the internet trying to find some hard dimensions for finishing a DPMS-style 308 80% lower without a jig. And for some reason, I can't find squat! I know that the safety/trigger/hammer pin holes are all located in the same relative positions as a standard AR-15 lower, but I need to confirm locating dimensions to any of these holes from either the pivot or takedown pin holes and the top deck. If no one has blueprint dimensions, maybe some folks could measure their lowers or jigs?
I know there is plenty of information out there for Armalite version, but I've heard these particular dimensions are not common between platforms.
Help please, I'm dying to cut some chips on my 80%er, but don't want to spend the $$ to get a jig if I don't have to!
