No. You should not order it because you cannot have it in your possession until you have a legal configuration for the upper. Whether it be a pistol lower, SBR or MG. The upper itself is not a firearm, that is why you can order it directly to your home, but make sure you don't have all the pieces to make a sbr, because even if it's all apart, it's illegal. So it's not about actually having it attached to your lower, it's about having the pieces to make it.
