Just purchased a nice 3D printer - got the AR-15 specs from the internet. Now I am "printing" functional semi-automatic .223 military style rifle in my garage!! Bah, to all their bans and all the B.S. - 2nd amendment trumps all - I will not comply with any of the constitutional violations occurring in D.C. I am granted the rights to bear arms of my choosing as a free citizen. I think an impeachment might be in order for violation of oath of office!
