Online registered a single M4 type BB equipped rifle built on an already registered at time of DROS factory lower on June 26, 2018. (I actually bought this lower after the BBAW law passed, but before it took effect, in order to be able to take advantage of the new registration window triggered by the BBAW law.)
Received "Processing" Email from DOJ on Oct 12, 2018.
Received confirmation letter dated Oct 16, 2018 on Oct 23, 2018.
***The confirmation letter also includes the rifles I registered in 2000 under SB23. Nothing about the letter indicates which rifles were registered during which registration window. The BBRAW is not separate from the RAWs. In fact it appears in the middle of the list, so its not even chronological order. No description of the firearms on the letter beyond; make, model, type (rifle /handgun/shotgun), caliber and serial number.
