So I finally managed to pick up the AWS 308 receiver set from the group buy. Show my LTC, provide my pin, fill out the paperwork, all is smooth until the shop calls NICS. Turns out that the transfer option is no longer available, an hour and 15 minutes on hold, shop gets told that they must handle the transfer as a handgun purchase. This results in it having to be inputted into the Mass system as well. My question to the shop was that since the lower has now been registered does this nullify the need on my part to fill out the F10 once the receiver is assembled and capable of firing a round. He did not have an answer. This had been the first time he had run into this problem. However the rep at NICS told him that they had been running into the problem all week and didn't have an answer either other than that all lower receiver transfers now had to be handled as a handgun transfer. Anyone have any ideas or also run into the same problem?
