I was told by a gunsmith that if I register a firearm on a BATFE Title 1 form (say I want to SBR an AK74) then it would be legal for me to have a collapsible stock and/or a flashhider. Since it would now be registered in the NFA registry it is exempt from MA AWB law? Does anyone know if there is any truth to this? The rifle is brand new so not preban. I cannot find the law anywhere to support this statement so thought I would post it here...
