  1. It would have save more lives in Vietnam if soldiers had these AR15s in the battlefield, more advanced than those Armalite SP 101s that would jam & didn't have the forward assist button.

  2. Thank you for this awesome, clear and detailed video! Lost 2 detent pins, the takedown and pivot, and am currently waiting for the replacements to be delivered… I'm now confident that I will get everything back together correctly!

  3. Wow that was very well detailed and I appreciate the up close views so I know EXACTLY what to do good job. The only problem I have now is that I cannot find a wrench long enough to fit into the grip…bummer
