For what it is worth I purchased an Upper from MidwayUSA. When I purchased it the status was on back order and it would be received 9/5/2012. then I checked back later and the date had changed to like 9-12-2012.
I ordered it back on July 4th, 2012. I just now checked and now the receive date to midway is 10/21/2012.
So there must be an overwhelming demand for uppers. mine is for an AR pistols and I cant find it anywhere else.
Sometime you just have to forget about something and wait.
1 Peter 3:15
But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect
2 Corinthians 3:3
You show that you are a letter from Christ, the result of our ministry, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
