Is this new? When I got my M1 through the DCM they shipped it directly to my house. No C&R.
No C&R needed to accept from CMP, (Special direct to door deal) C&R can be used to satisfy marksmanship/firearms use requirement (ABAICR)
They act as ffl if you don't have ffl 03
The part I quoted.. "except cmp"
Cmp does the nics check (they are ffl and only allowed sale ifnyou have proper documents required)
