I am new to this forum also. I just got two mags from S&W which I ordered a couple of weeks ago. I had called about them and was told that they were on back order and had been shipped that day. That is why you didn't get them. They have them now. Also, I bought my M&P 15-22 a couple of weeks ago from "Shooters" for $399.00 (plus shipping - total= $424.00). I had the exact same ejector problems. I posted this somewhere else and referred to the video that I saw about the fix. I also want to thank you so very much for making the video because hearing it described is not near as good as actually seeing it. I think that you did a great job and I, along with countless others, I'm sure, am very grateful. I shot five shots, no problem, then, every other shot was a FTE. Once I got out my needle nose pliers and did "the fix", no more FTE. Again, thank you and I hope that you had a very, merry Christmas! Also, we will all have a Happy New Year with our M&P 15-22's, now that we know the fix!
