  1. They should have done better in explaining to the soldier how the gas works inside the bolt, forcing the two sections apart to unlock it before sending it rearward. They should have shown the gas sealing as well. An animation should have been shown for that, since this is the very thing that fouls up in these rifles. Dirt and carbon buildup inside the bolt creates failure.

  2.  @riflesfirst208  are you gunsmith or armorer? I am. The carbon and dirt damages the sealing of the bolt halves, which was why they had to add a dust cover. It's also why there have been redesigns using a piston assembly and action rod to replace the gas tube, which does away with gas entering the bolt altogether.
