Anyone know of a place that has any AR15 complete upper halfs in stock? Everywhere I have tried is backordered. I had orders in to Model 1, JSE, DSA, and canceled them all after 6+ weeks of waiting. I tried delton and a couple others that have slipped my mind at the moment, everyone is backordered. Anyone know of a place selling a basic 16" M4 or midlength or lightweight upper that is in stock?
