FTF & double feed with PMAG!
Today I was at the Horno range for first day of rifle range. I brought 4 earlier gen PMAGs, 4 Rev-M PMAGs and 4 Lancers. It started to get windy, rainy and of course muddy. I shot fine but right before the 2nd string of 300yd rapid fire, at the command of "Load make ready" I had a double feed with one of my non Rev-M PMAGs. While everyone began to shoot I ejected the mag to clear the double feed, reinsert and began firing. I had a FTF at my 5th or 6th round and finished by of course, tap rack bang.
Has anyone had any similar issues? It really surprised me when it happened. My other PMAGs and Lancers ran just fine, even in the rain and mud. I just took it apart and besides being wet there's not mud or grit.
Any help is appreciated...
