This is probably the best 11 minute explanation on the AR-15’s cycle of operations I have seen.
The coverage of the mechanics involved and the interaction of the parts when used is simply explained and covers a wide range of individual questions.
The attention to detail of the individual parts groups is exceptional.
While the topic here is the AR-15, the understanding of how the system is operating conveys a much broader understanding of modern service rifles with similarities to the AR.
I love these finds. Enjoy!
