It is NOT illegal to build a HBAR!
It is not "illegal" to build any "legal" firearm.
Creation of a 100% lower from an 80% after 10/1, constitutes possession of a banned firearm due to the lower receiver being the firearm and also being banned by FSA 2013 as a receiver. Read the law and do your research. If you complete an 80% into a 100% now you will be breaking the law.
Also if you have any other AR's with government profile barrels on then, they can and will charge you for possession of a banned weapon that was not grandfathered in before 10/1, due to constructive intent. I wouldn't complete an 80% either in state or out of state and bring it back. No matter how you cut it, you will be breaking state law by doing so.
