    Going to do my first AR10/dpms barrel and I haven't been able to find any clearances and just generic dimensions (see below).

    Anything lug face clearance to barrel face? I fit my bolt guns (r700) for around .007-.008 pre crush, are they similar on a precision gasser? Looking for a range like .005-.010 or whatever is supposed to be. From then the rest is pretty simple.
