Ok she's finished but not without a problem. Every couple rounds, the round gets jammed up right on the feed ramp, pushing the bullet partialy back into the casing! I drop the mag, throw the round away and re-load. Very annoying to say the least having to do this every 2 or 3 rounds. So AR experts, what's ur opinion? Buy a new mag?,(they all tell me get the ones with the green followers) shine the feed ramp? What causes this chambering failure. Seems like a feed issue so I'm guessing buy a beter magazine?
