80% polymer AR-15 and pistol frames
Polymer80 is an American firearms parts manufacturer, focusing on so called 80% lower receivers. 80% receivers are almost-completed pieces of machined metal or plastics that are not classified as firearms by the ATF. As such, they can be bought, sold, and transported without restriction, as the government just considers them pieces of metal and/or plastic and not guns. Their motto is “Reluctor Dominatus”, which means “Resist Tyranny”.
