Hi all, I am trapped in the commie state of Mass and looking to buy but not sure I want a sig speer LT type, and would like to build my own AR copy from a stripped down lower so I have a few questions like how the hell is the sig speer on shelves but not AR copies here in Mass?!!? Secondly what is the "gray area" to buying a stripped down lower and building a complaint version and submitting all the proper forms? Can some someone please explain this process? Thanks
