If you shoot long enough you’ll eventually get a jam or malfunction of some sort. Jams are usually caused by dirty guns, low quality ammo or mags or just a crappy gun. Check out the video above, a shooter at a class has a jam with his AR-15 caused by a bee that flew into the chamber. He’s doing everything he can to clear the jam until he finally looks inside the chamber and sees the bee in there. I bet an AK would still fire.
Imagine if that happened in a combat situation!
