No, those are the Armalite pattern measurements.  Hopefully I'm not breaking the rules here.   I'm in no way affiliated with this company, but the posted the measurements you're looking for on another forum here:  http://www.calguns.net/calgunforum/showthread.php?t=756641    Scroll to the bottom of post #2

If you look at Page 2 of the PDF, you can clearly see that it has an angled magazine well, which is for the M14 derivative magazines.

Sorry I didn't specify, but quenton defense and tactical machine lowers are dpms style. Armalite, kac, lmc are not. The blueprints I linked are the ones that you need.

Those Dims seem correct, and yes the QD-308 are DPMS AR-308/SR-25 pattern compatible.
I will check them against my AR-308 prints and confirm those dims...

The Armalite AR-10B lowers have dimensional differences when compared to the DPMS LR-308/AR-308 pattern...they
especially differ in the Internal magazine dimensions vs. the DPMS/SR-25 pattern versions...

The QD-308 prints are (after doing a very quick dimensional check) within "spec" in the critical areas of the fire control
and rear shelf pocket area, etc.

The fire control areas of the AR-308 and AR-15 lower receivers are very similar dimensionally (as they were designed
to be, ala SR-25 pattern and the DPMS LR-308 for the most part).

Good Luck.

The pocket dimensions are all the same between the AR10 / SR-25 / DPMS / AR-15. The pocket and holes are relational to each other.  In the case of the AR-10 and DPMS pattern guns the pocket and holes are not in the same place.  30ths difference in location. You can find the correct location by using the hold made for the selector detent to place the pocket and trigger / hammer pin holes.
