  1. I swapped out the entire stock for one made by Black River Armory.

    It's a five-position collapsible stock that functions exactly like the AR platform. It also has recoil buffer springs in it.

  2. Thank you! When the gun locks back, do you need to close the bolt to reload it, and then hit the shell release again? If you don't press the shell release but you rack the bolt, does it not pick up a round?

  3. Great intro video. Couple "more advanced" tips I would add:
    – the stock has 2 lock positions for those of us with shorter arms, but keep in mind the shorter position raises your cheek and alignment with optic.
    – it is much easier to load the M4 with it upside down and the receiver facing up. This becomes more difficult with a sling, but with no sling, load it upside down.

  4. May I suggest, A bunker, because when China sinks a US naval vessel and lose more service people since the Vietnam war, Birthplace ain't going matter.
