    Post 10/1/13 lower receiver can't be built with lightweight barrel. HBAR, AR pistol or SBR only. You can buy everything online except the lower receiver, that transfers through an FFL with the MD form and 7 day wait (unless you opt for an 80% lower)

    If you buy the stripped or complete lower (not 80%) it is "registered" when you purchase. After that just build a pistol or hbar. No further registration needed. If you buy an 80% lower you can even skip the entire "registration" part. No FFL needed.

    What do you mean by 80% lower ??? do you mean 80% complete

    Yes, buy the 80% completed lower and a jig, drill bits etc, (I think about $100 investment for the tools) and you can build all the AR's you want (Just make sure you build a "Maryland Legal" AR. The 80% lowers don't require an FFL or background check or "voluntary" registration with the state.

    So then the gun is a wall hanger at that point , what if I would finish the other 20% ???

    I do not have an evil black gun as of yet , just trying to figure things out .
    It becomes a gun when you finish it but homemade guns don't have to be "registered".

    Legally speaking, if you first build it as a rifle, you can not turn it into a pistol. You can turn it into an SBR after receiving your stamp from BATF.
