I have put about 700 rounds through my 24/7 with not one problem. Now I am having FTF and smileys on the bullet nose. I have cleaned the magazines extensively and even smoothed the edges of the magazine follower with sandpaper. It happens with the first four to five rounds and then it doesn't do it with the last five rounds ( I have the 12 rd mags but only put 10 in ). Anybody have any good ideas because I am at a loss here. Thanks
