Shooting my HK MR556 using cheap American Eagle 55gr range stuff with an old 20rd mag and I notice the gun has failed to go into battery. Weirdly the round was on top of my bolt (see pic). Thankfully I was able to work the round out with a lot of effort and pulling the bolt back and forth.
Any idea what happened? I’m guessing it was magazine related since I switched to a new magpul and everything worked fine from then on.
