I'd like to build a billet AR10 lower using the new Armalite AR10A lower specs from Justin's CNCGUNS AR10B solid. I already know that you need the Armalite AR10A upper, bolt hold catch and mag release; all I'm missing is the magwell dimensions.Link to Armalite's Tech notes
Armalite tech manuals specify that the main difference between the AR10A and AR10B lower is the increased upward angle of the bottom of the mag well (which makes sense in that the M14 mags are straight and the SR25 have a Slight angle).
I was wondering if anyone had the exact specs for the either the new AR10A or the DPMS 308 magwell or know if Justin solid which looks like it already has the upward angle would take the DPMS pattern mags
This is what it'll look like when it's done:
