I have four complete New Frontier Armory AR-15 Complete polymer lower receivers with 6 position collapsible stocks, ambidextrous dual sling plate adapter, and a 1 point bungee sling. Lower is ready to pin onto your upper. The lower is what is considered the firearm on an AR-15 and is what would be banned if a ban were passed, Price is $300 per lower receiver face to face in Springfield, MO or will ship for $25 to your FFL in a state they are legal to own. Can also include a stock wrench if you want for no charge. If someone buys all 4 I could work out a better deal.
