Has anyone purchased a .308 lower receiver this year? I recently moved to Maryland and was trying to buy an Aero M5 stripped lower this past week, but my LGS was unable to process a background check. Apparently the NICS call center is saying that all "other firearm" transactions must be processed by the state police as of January 1st. The state police are saying that they don't process large frame lowers because they are not part of a regulated firearm. The LGS went back and forth between the two the following day until the state police stated that the FBI had revised their system incorrectly and that I would need to wait until they acknowledged and fixed the error. So, for now, it seems that my lower is stuck in limbo for an undetermined amount of time.
