Clueless n00b here, but I have been searching in this regard as well.
I have taken a look at local ranges and haven't found any that are especially "friendly" (in my estimation) to full-auto.
cf.
Weeping Water rules:
"18. Members must obtain prior permission and must be in possession of signed documentation from the Board of Directors to shoot “fully automatic firearms or firearms of .50 BMG or similar large cartridges on WWGC property. Guest shooting these firearms must be directly supervised by the member. 50 BMG’s will fire the far left lane on the rifle range out from under the overhead. Full autos “INCLUDES RAPID FIRE TRIGGER DEVICES” will use only the short range end of the rifle range. Auto fire is limited to 3 round bursts, no full auto 50’s."Again, I am new to all this (and not a member of Weeping Water, so others are more qualified to comment about this), but I didn't find the requirements for prior approval and "limited to 3 round bursts" especially accommodating. Then again, it's better than a "no NFA" rule.
