The lawmakers don't know about them (10-22 rifles), so they are legal for now.
Sort of like the Taurus Judge or Taurus Public Defender revolvers---they can fire shotgun rounds (4-10 pellets or 4-10 slugs) and have a barrel less than 2 inches long. Seems like these revolvers would fall into the illegal Sawed Off Shotgun category if a lawmaker knew of there existence---however, as of today they can be legally bought in the USA.
