While I was at the range the other day, on either my second or third shot after firing, my trigger didn't reset and the rifle just went click. I ejected the magazine and cleared the chambered round. After clearing the chambered round I reloaded the mag and the rifle shot another round but the same thing happened. I did the same thing but this time around it was very difficult to eject the magazine, I really had to push down on the magazine release button to get the magazine to eject but after a little force pushing the magazine released and after following the same procedures, my rifle began to work again as normal. Mind you this only happened twice and it never happened again afterwards, but I was wondering what it was that caused this happen.. I'm guessing I either had a double feed or some other problems with the magazine (10 round stag arms mag, that came with my rifle). Maybe someone else could give their input as to what they think the problem might be. Going back out to the range tomorrow and I'll see if it happens again. Thanks again as always.
