Once this part is assembled into a complete firearm, it becomes a regulated item by the National Firearms Act (NFA). Please check with your local and state municipalities for any further regulatory requirements. It is the buyer's responsibility to make sure they comply with all NFA rules and applicable laws. Note that if you have a receiver that is designated for use with pistol buffer tubes and not a stock, it could be assembled into a functioning pistol without the NFA Tax Stamp to possess what would otherwise be a SBR.
