For sale/trade I have an ATI OMNI polymer lower. It comes complete with a stock and lower parts kit installed. No rounds have been fired from this lower at all. It's been attached to different uppers and function tested, but no rounds have been put through it. I"m asking $200 obo or I'm willing to trade. Trade interests would be silver coins, AR-7 survival rifle, Ruger 10/22, Norinco 213 in 9mm Luger, or ??? Feel free to offer anything firearms related.
